Any of these 3 textbook options will be sufficient for your courses Math 1225, Math 1226 and Math 2204. • There is a two week grace period all students enrolled in Math1225 to access WebAssign, and thus to the ebook access. After that time you need a purchased WebAssign code. How to access WebAssign the first time • You must access WebAssign through Canvas. Do not attempt to login directly. Instead access each WebAssign Quiz via Assignments. • If you had purchased the 8th edition of the Stewart textbook for Math1225 during a previous semester at Virginia Tech, you do NOT have to buy the new edition and can use your current WebAssign account. You should automatically receive access if you purchased multi-term access. However, if you do not have access you may contact Rachel McCoy (rachel.mccoy@cengage. com) to have access to the 9th edition WA access. Working on WebAssign quizzes • All Homework assignments will allow at least five attempts per question. You are graded questionby-question, with the best score on each question from either attempt being used. Note that for the questions that have multiple parts, all parts should be submitted, even if the parts were marked as correct in a previous attempt. • Be aware of the time. WebAssign will log you out and not tell you after some time. This will result in your answers just vanishing. Save you answers often to prevent this. • After the due date of a homework assignment, you can click on the assignment link to access the ”Practice another Version” and the ”Solution” features of the system. In particular full detailed solutions are available for each problem after the due date for you to study. Tips to avoid mistakes Working with WebAssign can be tricky. When entering your solutions pay attention to the following: • Questions are graded separately, but parts of a question are graded together.If you want to get full credit on a multi-part question, you must get all parts correct. In particular do not leave empty parts even if you already filled them and got them right in your previous attempt. • Our WebAssign quizzes should be submitted as a whole. It is recommended to save your work constantly. You want to submit your first attempt only after all the questions have been answered. • Be careful with your parentheses. Make sure they match. Make sure that you are providing parentheses when they are needed, and not putting them when they are provided. Be careful with capitals. WebAssign treats C and c differently. This includes Greek letters. Use the lower-case pi. It is curved. • Be careful with functions. If you enter a trig fuction by typing (rather than using the menu) make sure to include parentheses. Don’t use the function ”e” if you mean the constant. • If you answer still has a box in it, WebAssign won’t be able to understand it and you will be marked incorrect. • WebAssign treats a number (like 12 21 ) as multiplication, so an answer like that would be counted correct for a problem whose answer is actually 6, but incorrect for a problem whose answer was 25/2. To enter a mixed number use the mathpad button . • Remember not to round if the question doesn’t tell you to. Most answers should be exact. Even if your final answer is going to be rounded, use the exact numbers until the end. • If you are unsure on the rule to round, please check the information given by the WebAssign site: http : //www.webassign.net/manual/student guide/c a rounding.htm
