Algebra 2 Name ____________________________ Date __________Per ____ CONIC SECTIONS PROJECT / TEST (With One Partner) PARTNER: My partner is ___________________________________________. TITLE OF OUR DRAWING: ______________________________________________. OBJECTIVE: Create a picture that can be described by a series of equations of conic sections with restricted domains. GRAPHER: http://people.hofstra.edu/staff/steven_r_costenoble/Graf/Graf.html BRING: Your own laptop (optional) – bring at your own risk. Graph paper (Ms. Yu has graph paper too) – this is useful for hand testing the equations. 1) You must have AT LEAST 20 EQUATIONS. These must include conic sections but can also include linear, exponential, or trigonometric equations. at least 20 equations 2) Out of the 20 equations, 12 of your equations must be 3 of each different type of conic section (parabola, hyperbola, ellipse, and circle) in your picture. For all conic sections except the circle, there must be at least one vertical and one horizontal shape. Each partner must do at least 10 of the total equations and at least 1 of each conic section. Parabola – vertical Parabola – horizontal Parabola (any direction) Initial: ___ Initial: ___ Initial: ___ Hyperbola – horizontal Initial: ___ Hyperbola – vertical Initial: ___ Hyperbola (any direction) Initial: ___ Ellipse – vertical Ellipse – horizontal Ellipse (any direction) Initial: ___ Initial: ___ Initial: ___ Circle Circle Circle Initial: ___ Initial: ___ Initial: ___ _________________ _________________ _________________ _________________ Initial: ___ Initial: ___ Initial: ___ Initial: ___ _________________ _________________ _________________ _________________ Initial: ___ Initial: ___ Initial: ___ Initial: ___ This is just a check list. You can use more equations than the amount listed here. 3) DOMAIN RESTRICTIONS. At least 10 of your equations must have restricted domains. Eq #___ has domain restrictions. Eq #___ has domain restrictions. Eq #___ has domain restrictions. Eq #___ has domain restrictions. Eq #___ has domain restrictions. Eq #___ has domain restrictions. Eq #___ has domain restrictions. Eq #___ has domain restrictions. Eq #___ has domain restrictions. Eq #___ has domain restrictions. YOU ARE REQUIRED TO TURN IN: 1) This packet with the check list and initials. 2) Homework Equation Sheets – the equations that YOU did, solved for y by hand. It’s okay if these are “rough draft” equations that you didn’t end up using. These equations must be different than your partner’s. 3) Final Equation Sheets – the final equations the YOU did, solved for y step by step, hand written or typed. These are YOUR half of the equations being used in the picture. These equations must be different than your partner’s. Number the equations and these should correspond to the same labeled numbers on the “Type into Grapher” Equation Sheet. Include important information about conics: Circles - center and radius. Ellipses - center, x radius, and y radius. Hyperbolas - center, x radius, y radius. Parabolas - vertex 4) “Type into Grapher” Equation sheet - a list of ALL the equations used to create the picture in the exact form in which they were typed into the computer, the shape requirement that they fulfill, and the location in the picture. Number the equations on the sheet and on your print out. (Copy and paste from your online file, and then label the equations.) You can your partner can print out the same copy of this. 5) A print out of your graphed picture with the grid from the Grapher. 6) A large (at least 8.5” x 11” but no larger than 11” x 14”) copy of your picture carefully graphed and colored or decorated to make an attractive picture. You may cut out your picture and paste it onto a hand-drawn background. (ONE COPY SHARED IS OKAY.) GRADING: Projects will be graded on the equation and partner requirements above, creativity, difficulty, carefulness, and accuracy. Neatness counts. You may type your math, but it is not required. Writing must be legible and neat.

Careful choice to make maximum use of limited graphing Decorative Picture Looks artistic, color, well presented Careful graphing: All lines intersect exactly where appropriate. Lines and shares easily included were not left out. Scale and axes are present and square Picture fills 8.5 by 11 Neatness Orderly, clean, and tidy. Neat handwriting or typed. Accurate Equations All included forms of equations and restrictions are accurate. Calculations of foci radii, centers, focal points are accurate. Careful Presentation Readable, Sections are coherently organized to facilitate analysis. Carefully written or typed. Complete presentation All required elements are included. Degree of Difficulty How many equations were used. Complexity of equations used TIPS / FAQ (Frequently Asked Questions) – CONICS PROJECT GRAPHER QUESTIONS: 1) What is the best way of typing equations into the Grapher and saving my equations? 1) Test each equation individually on the Grapher first. 2) When an equation works, save it in a word document. Separate each equation with a semicolon “ ; ”. When you would like to test out a bunch, copy and paste all of them into the Grapher. NOTE: If there is one mistake in the typing, the Grapher will not work. NOTE: Your last equation cannot have “ ; ” after it. 3) At the end of the day, email and cut & paste the most updated equations back to yourself. 2) What if I only want to graph in Quadrant I (only positive numbers)? Change your Min X, Max X, Min Y, Max Y to show only the boxes you want to see or zoom in to. 3) How do I count the boxes if Hosftra Grapher only shows the axes and intervals? Put a piece of graph paper transparency on top of your print out and compare the boxes. 4) How do I print out my graph? Press the “Print Screen” or “Prnt Scr” button. Then, go to Paint and paste. From there, print. With the grids don’t change anything Without the grids unclick “Show X/Y Ticks” unclick “Show X/Y Scale” EQUATIONS, SHAPES, AND REQUIREMENTS QUESTIONS: 5) If I graph an entire ellipse/hyperbola/parabola and have to split it into 2 equations because it is not a function, does that count as 1 equation or 2 equations? Answer: 1 EQUATION. 6) How do I get weird shapes that we haven’t learned yet? Like diagonal parabolas? Combine a bunch of known shapes together, using lots of domain restrictions. Or, look up in a math book or the internet on how to graph diagonal conic sections. 7) How do I solve for y? Look at your notes. 8) What counts as a domain restriction? NO half an ellipse, half a circle YES anything where you have to do “ … / (x>#smaller & x<#bigger)” Example: 0; (4/5)(25-x^2)^(1/2) ; (1-(x-2)^2)^(1/2) ; (1-(x+2)^2)^(1/2) ; (3(x-13/2)^2-1) / (x>6 & x<7) ; (3(x-15/2)^2-1) / (x>7 & x<8) ; (3(x-17/2)^2-1) / (x>8 & x<9) ; (3(x+13/2)^2-1) / (x>-7 & x<-6) ; (3(x+15/2)^2-1) / (x>-8 & x<-7) ; (3(x+17/2)^2-1) / (x>-9 & x<-8) ; (3(1+x^2)^(1/2)-4) / (x>-3/4 & x<3/4) Line NO Half ellipse (not a restricted domain) NO Half circle (not a restricted domain) NO Half circle (not a restricted domain) NO Parabola (restricted domain) YES Parabola (restricted domain) YES Parabola (restricted domain) YES Parabola (restricted domain) YES Parabola (restricted domain) YES Parabola (restricted domain) YES Half hyperbola (with restricted domain) YES ALG2 – CONICS PROJECT Name __________________________ Date ____________ Per___ HOMEWORK EQUATIONS SHEET(S) DAY #_____ SHAPE: ______________ Equation in Standard form: Type into Grapher (include any domain restrictions): Sketch on x-y-axes: Solve for y: Vertex: ________ Center: ________ Radius: _________ Xradius: ____ yradius: ____ Asymptote: _____ SHAPE: ______________ Equation in Standard form: Type into Grapher (include any domain restrictions): Sketch on x-y-axes: Solve for y: Vertex: ________ Center: ________ Radius: _________ Xradius: ____ yradius: ____ Asymptote: _____ SHAPE: ______________ Equation in Standard form: Sketch on x-y-axes: Solve for y: Vertex: ________ Center: ________ Radius: _________ Xradius: ____ yradius: ____ Asymptote: _____ Type into Grapher (include any domain restrictions): ALG2 – CONICS PROJECT Name __________________________ Date ____________ Per___ HOMEWORK EQUATIONS SHEET(S) DAY #_____ SHAPE: ______________ Equation in Standard form: Type into Grapher (include any domain restrictions): Sketch on x-y-axes: Solve for y: Vertex: ________ Center: ________ Radius: _________ Xradius: ____ yradius: ____ Asymptote: _____ SHAPE: ______________ Equation in Standard form: Type into Grapher (include any domain restrictions): Sketch on x-y-axes: Solve for y: Vertex: ________ Center: ________ Radius: _________ Xradius: ____ yradius: ____ Asymptote: _____ SHAPE: ______________ Equation in Standard form: Sketch on x-y-axes: Solve for y: Vertex: ________ Center: ________ Radius: _________ Xradius: ____ yradius: ____ Asymptote: _____ Type into Grapher (include any domain restrictions):
