AP Calculus Syllabus 2010-11 Please take the time to thoroughly read this syllabus. All students are responsible for its content. This syllabus should be kept in your math notebook and periodically reviewed as needed. Summary of Course: AP Calculus will introduce and study the topics of functions, graphs, limits, derivatives, and integrals. We will focus on giving students the opportunity to work with functions represented in a variety of ways, including graphically, numerically, analytically, and verbally and stress the connections among these representations. Students will be using TI-83+ graphing calculators and MacBook laptops to help solve problems, experiment, interpret results, and support conclusions. A fair amount of instructional time will be devoted to learning how to properly use your calculator to help accomplish these tasks as they arise. The overall goal of this course is to master the material outlined above to an extent where the student will be able to successfully pass the AP Calculus AB test. Students will work both in groups and individually. Learning will be facilitated through direct instruction, practicing problems, group discussion, and project based learning to explore mathematical applications. Expectations are high regarding the quality of student work. Units of Study: 1. Review Functions, Graphs, Rational and Polynomial Functions: a.

Grading Policy: Homework- As this is an advanced placement class and is designed to give you college credit for Calculus, your homework will be graded the same way it would be graded in college. I will not grade homework and it will not be part of your grade. Homework will be assigned on a daily basis and you will be expected to do it by the next class period. We will go over the answers as a class and answer any questions you may have at that time. Since it is important to understand different approaches to solving problems, we will spend extra time discussing how to use your calculator to solve and check answers. Just because homework is not graded does not mean you should feel as though you do not need to do it. I will keep track of who has their homework completed on time, but again, it does not factor into your grade. Homework = 0% of overall grade Participation/Effort- As in college, you are given no credit for simply showing up and doing what you are supposed to do. You are expected to be in class on time and prepared to learn every day. If you are gone a great deal, it will no doubt reflect in your grade without me calculating it in. What you do receive participation credit for is successfully completing tasks such as answering questions at the board, teaching a review topic in preparation for a test, etc. You must become skilled in the art of communicating math, both verbally and in writing, so you must practice, practice, practice! Special focus will be placed on showing how you arrive at your answer using both your long-hand math skills and also your calculator. How do you use the calculator to check your answers? Participation/Effort = 10% of overall grade Tests/Quizzes- Short quizzes will be given regularly and usually consist of one or two questions taken from the AP Calculus practice test question bank. You will not be given notice and will only be allowed to use materials that you would be allowed to use on the AP Calculus test. Quizzes will always be given directly after we have gone over homework and you have asked questions about it, so make sure you understand the material or ask questions before we move on. Tests will be given at the end of each unit of study and will encompass all work completed during that unit, and will also include topics covered in past units. The tests will consist of two parts. The first part will include you presenting one or two random questions to the class. This part of the test will be graded on your correctness, but also your ability to communicate mathematically both verbally and in writing on the board. The second part of the test will be written and will follow the same structure as the AP Calculus test, including what materials you are allowed use. Tests/Quizzes = 60% of overall grade Projects, Presentations & Class Work- Projects and presentations are an important part of this class. It is not simply enough to be able to answer questions, you must be able to apply your knowledge to real world situations and be able to accurately and effectively present your findings to others in a variety of ways. Specifics on projects will be given out during the year, but you can expect to average one major project every two units. Just as in the business world you would not get paid (for very long) if you did not finish the tasks assigned to you, in this class you will not get a grade on a project until it has met a high standard of quality. If your project does not meet this standard, it will be returned to you until it is finished. However, if it is not finished by the deadline, expect your grade to suffer as a consequence. Refer to the Projects portion on the next page for more detail. Projects, Presentations & Class Work = 30% of overall grade Grades are awarded as follows (round decimals to nearest percent): 92% and above 88-89% 78-79% 68-69% Below 59% A B+ C+ D+ F 90-91% 82-87% 72-77% 60-66% AB C D 80-81% 70-71% BC- Required Student Supplies: A graphing calculator (a TI-83 Silver Edition or TI-84 is strongly recommended) A spiral bound notebook with pocket (preferred) or section within a three-ring binder exclusively for homework assignments. Pencils and erasers Graph paper A covered textbook (provided) Projects: The following is a sampling of the projects we will complete throughout the year. This list is subject to change but adequately give the reader an idea of the type of work we will be doing. These projects were found at: http://www.mecca.org/~halfacre/MATH/proj.htm When possible, I will let students search for their own projects. They will have to be checked by me for appropriateness, but you should spend time working on a topic that you find interesting. All projects must be completed in written form and/or powerpoint form as you will also have to report your findings to the class when finished, with special focus on communicating the math involved in your solution. In each report, aside from reporting your results, I would like you to describe how you used your calculator to help solve the problems. OptimizationA Dorm Room's a Dorm Room, No Matter How Small After months of diligent work, I finally earned a promotion to Vice President for Development here at Who-U, which shocked quite a few Whos because, as you probably know, I am not more than two. Oh, they tried to just give me a drink of water and send me to bed, but I worked very hard on our outreach to other dust specks. I'm very proud of my fund-raising accomplishments, but sometimes the gifts come with very strict limitations on how they can be used. We just received such a donation, and when I went looking for help, your enterprising and resourceful professor naturally referred me to you. We have a somewhat eccentric alum who has made a major contribution in memory of his favorite Chia Pet Airplane that recently passed away in a bizarre gardening accident (it's best we not discuss the details). As a fitting tribute to the dearly departed, the donor has designated that the funds be used to build a dorm in the shape of an airplane hangar, as shown below. There is an additional stipulation on the gift: the volume of the dorm must be exactly 225,000 cubic feet, which is one cubic foot for each sprout on the Chia plane. We're in the planning stages with the architects now, and we would obviously like to minimize the cost of the building. This is where I need your help. Currently, the construction costs for the foundation are $30 per square foot, the sides cost $20 per square foot to construct, and the roofing costs $15 per square foot. I need your expert advice on what the dimensions of the building should be to minimize the total cost. While the cost of the flooring and siding has been fairly stable, a further complicating factor is that the cost of roofing material has been fluctuating dramatically for as long as I can remember (at least two months). In addition to your recommendation for the price of $15 per square foot, I also need a recommendation on the dimensions of the dorm if the roofing costs $R per square foot. We are meeting with the architects to discuss plans before Thanksgiving, so I would appreciate your report by November 11. It's nap time now, Cindy Lou Riemann SumsDear Calculus Students: I recently became CEO of Spacely Sprockets after a somewhat messy hostile take-over, and I do not yet trust anyone at the company to help me with the critical decisions that will affect the success of the corporation. When I went looking for help, your enterprising and resourceful professor naturally referred me to you. I am remodeling my (nearly) oval office and replacing the horrid orange carpeting left by my predecessor. With the Board and shareholders watching my every move, I want to be careful not to appear profligate. I have already decided on a tasteful aqua shag, but the carpeting comes on rolls in three different widths: 2.5 yards wide, 1.5 yards wide, and 1 yard wide. I will use the same width for the entire office, but I'm not sure which one to choose. For each of the three widths, I need an analysis of how many square feet of carpeting I must buy and an estimate of the amount of carpeting that will be trimmed and wasted. I also have the option to special order the carpeting in any width. To impress the board with my thoroughness and allaround competence, I would like to know what width I should order so that no more than 15 square feet of carpeting are wasted. I am including a sketch of my office, and I would appreciate an answer by October 1 since I need my office to be ready for an important meeting later in the month with AOL-Time-Warner to discuss the launching of the Sprockets Channel (``All Sprockets. All The Time''TM). Exponentials/Newton’s Law of Cooling- Dear Calculus Student: I have a difficult problem for which no one in my factory can find a solution, and I hope that you can help me. Your intrepid and enterprising professor, Dr. Crannell, referred me to you. At the Jumping Gelatin Factory, we make 42 different flavors of gelatin and provide all the gelatin for all the local day-care centers and nursing homes, as well as for numerous fraternity and sorority parties. Because of this, turnaround time is extremely important to us, and lately we have become increasingly worried about the amount of time it takes to mix and cool our food product. As you may know from making gelatin at home, the preparation process is this: The gelatin powder is added to a quantity of boiling water and stirred at the same temperature until it dissolves. We have experimented with the time needed at this stage and have discovered that 2 minutes is the shortest amount of time we can take and still maintain the high quality of our dessert. The next stage is to remove the gelatin from the burner. At this point we add ice water (the same amount as the boiling water) and wait for the dessert to gel. It is at this stage that we are hoping to improve our efficiency. There are some people here who believe that the ice water should be added immediately; others believe that it should be added bit-by-bit; and still others believe we should wait an hour and then add the ice water. No matter which of these procedures we use, national gelatin guidelines proscribe that one hour after the gelatin is dissolved, we must place the entire mixture into a refrigerator and remove it only again when gelled. Of course, the cooler it is by this point, the faster it gels. The refrigeration temperature is also mandated, and so that can not be changed. The question I have for you is: Given the procedure described above, in what manner should we add the cold water to cool the mixture the fastest? I would appreciate an answer as soon as possible, but hopefully no later than September 30, (our budget is due the day after). Distance, Velocity, and AccelerationDear Calculus Student: I am so incredibly sorry to be writing to you again; I know that this is a really busy time for you but I hope that you can somehow find the time to help me once more. As you might have guessed from the official letterhead, I'm in trouble with the law once again. I'm writing you from the BCPD jail, where I'm being (yet again) held on suspicion of murder. Here's how I got myself locked up this time: I went to visit the Absolutely Gorges, which have long been famous for being such a beautiful natural wonder, and which in the last few years have been famous because of the death of Bobo the Clown, who was shot out of a cannon and into the canyon nearly two years ago. At first it was believed that his death was suicide, but then some calculus students proved that the circus owner, Rick Rasterdly, murdered poor Bobo. At any rate, the site of Bobo's death has become quite a tourist attraction, and so I took a Saturday to go visit the place. If I'd known that my infamous ex, Jeremy, and his sleazy pal Sheriff Gocher were going to be there, too, I never would have gone. Gocher says that I followed Jeremy there, but I swear that's not true. In fact, I hardly saw him the whole time I was there, except for a few seconds it's those few seconds that are causing all the ruckus. What happened was I walked along the cliff-walk, like everyone else does. The cliff-walk is a steel walkway that winds along the face of the canyon and goes right by the place where Bobo met his end. It's pretty shaky and not very wide, and within minutes I was grateful I'm not afraid of heights, because there's quite a drop. The walk runs more than 1000 feet below the top of the gorge, but 3,280 feet above the floor! There's a bend in the cliff-wall right where Bobo hit; just before that, there's a gate where people can, as the brochure says, "punch your ticket", which I did. (There's a photo-copy of my ticket on the next page). Since the murderer was discovered by a trick of timing, everyone is asked to synchronize their watches at this gate, but I wasn't wearing a watch. You can't see around the bend from the gate, and so they use this as a natural place to charge folks: you have to pay $3 to continue on. So, I paid my $3, punched my ticket, and walked around the bend. I heard someone screaming, and thought at first it was some kind of joke, but as I came up on the place where Bobo died, I saw a person already falling down into the gorge, it was Jeremy, and he was the one screaming. I didn't even know it was Jeremy at the time, I just stood there, gripping the railing, staring awestruck. Suddenly Gocher ran toward me from further along the catwalk. He looked over the edge, saw the body, saw that I was pale as a ghost, and arrested me. Gocher says that I knew that he and Jeremy and some buddies were going to be there that day, seeing the sights. He'd been with Jeremy until about a minute before his death, but then left Jeremy behind in order to he catch up with the rest of the group. By now, he's quite pleased that he's got me it's revenge for my escaping last time. Jeremy's watch stopped at 1:54:09; the ticket puncher said that Jeremy had, along with Gocher and everyone else, set his watch to the official clock. My ticket, as you can see, was punched at 1:53:57. This gives me a whole 12 seconds to have walked from the punch, around the curve, and pushed Jeremy. At first I thought this proved I didn't do it, but when I counted out 12 seconds to myself, I realized it's a pretty long time. I just don't know what to do! I am so sick of this jail cell. Please do help to get me out! My preliminary hearing is November 11 (eleven-eleven: Deputy Dirk would have loved it, rest his soul!). If you could find a way to clear me before then, I'd be eternally grateful! VolumeDear Calculus Student: In these times of great concern over the health of our planet, there are few people who do not know about the overwhelming problem of waste disposal. We entrepreneurs at Eco-Sludge are not immune to this concern; in fact, we are directly responsible for disposing of the waste byproducts for the larger part of the state of PU. Unfortunately, our former board of managers, which has now been forcibly retired by the state's Environmental Agency, spent the greater part of its energies on improving cost-effectiveness to the grave detriment of safety and health. As a result, we are now faced with a expensive, and what is worse, dangerous cleaning project. One of the first tasks facing us is estimating the total damage done. Your keen and piercing professor, Dr. "Death" Crannell, told me of your resounding success with the Jumping Gelatin Factory, and so I am being so bold as to ask you for help. Our sludge is stored in large containers buried beneath the ground. These containers were manufactured with ease-of-construction in mind, and are really nothing more than parabolic holes in the ground, lined with concrete and covered with lids. (The problem is that the concrete cracks because of the changes in temperature due to our erratic climate. The sludge has been seeping out into the ground and making its way to the water supply. Needless to say, this is a horrendous state of affairs for our local fishers as well as for any inhabitant wishing to drink water from the faucet). There are several measurements concerning the storage containers that we can make with ease. Obviously, we can determine the diameter and the radius of the vat's opening with a large tape measure. We have a plumbing rod that we can use to determine the depth of the container and also the depth of the sludge (this is done much the same way you check the oil in your car: by pulling the stick out and seeing how much of it is wet). According to specifications, each vat should be 40 feet across at the top and 40 feet deep. In reality, we have found that the measurements of the vats vary significantly, although the general parabolic shape does not. And, to no one's surprise, there is neither rhyme nor reason to the depth of sludge found in a particular vat. What we can not easily determine is what we most need to know: the quantity (volume) of the sludge in any given vat. We are fairly certain that there is, however, a mathematical way of deriving this formula. We would be most grateful if you could help us with this, either in the standard (40'x40') case, or even better, in the more general case. Our report to the trustees must be mailed by November 6; could you please get the answer to us before that date? We await your reply with eagerness.
