1 CONIC PROJECT Algebra H DUE DATE: Friday March 15, 013. This project is in place of a test. Projects are to be turned in during your period, handed to the teacher. Projects may be turned in early (They must be handed to the teacher). Projects must be turned in on time to receive full credit. Student absence or tardiness will mark projects as LATE. o FOR ANY CONSIDERATION REGARDING EXCEPTIONS TO THE DEADLINE, CONTACT THE TEACHER BEFORE THE DEADLINE; THIS DOES NOT GUARANTEE AN EXTENSION WILL BE o MADE. Projects turned in after your class period on Friday 3/15/13 but by on Monday, March 18 th will be accepted, but docked 0 points. o Projects will not be accepted after 3/18/13. This is a group project with either 3 or 4 members per group. Once a group has been formed, it may not dissolve any members without the consent of the teacher. o o Group assignments affect the grade of all members in the group Individual assignments only affect the grade of the individual GOALS: Investigate the graphs and equations of conic sections. Use these equations to create designs and investigate planetary orbits. GRADING: This Project is worth 100 points. Grading is based on accuracy, neatness, completeness, grammar, and spelling.

3 PLANET AND SCIENTIST REPORT PLANET REPORT 1. This report requires both an accurately hand drawn graph and a written report.. To draw the graph, do the following: a. Find both the shortest and longest distance (in kilometers) from the sun to the planet you chose. b. The sun is one of two focus points (equidistant from the center along the major axis) inside the elliptical orbit of your planet. Use the following information and your notes to find values for a, b, c and then the equation of your planet s path through space. i. C is the distance from the center to a focus point. ii. The sun is one of the focus points. iii. a is the entire length of the ellipse through the center and both foci. iv. b is the entire width of the ellipse through the center. v. The longest distance = a + c. vi. The shortest distance = a c. vii. a b c c. Write an equation in standard form for the orbit of your planet. You must show supporting work to show how you found a and b. 3. Draw an accurate graph of your planet s orbit on a full-sized sheet of graph paper. Write the scale & units on your graph. Label the coordinates of the sun and the center on your graph. 4. Write a minimum 10 sentences, telling interesting facts about your planet. You must list the resources that you used. WIKIPEDIA (or any other virtual encyclopedia) may not be listed as a resource. MUST BE TYPED SCIENTIST REPORT Choose a scientist from the list below and write an interview which includes a minimum of 10 questions and accurate answers. You must include his/her connection to astronomy and/or mathematics and/or conics. A column format is acceptable. You must list the resources you used. WIKIPEDIA may not be used as a resource (Though the citations Wikipedia uses may be of use). MUST BE TYPED Edmund Halley Tycho Brahe Johannes Keplar Apollonius of Perga

4 REAL WORLD CONICS Write your answers and supporting work on graph paper. You must show supporting work for your answers. 1. Statuary Hall is an elliptical room in the United States Capitol in Washington, D.C. The room is 46 feet wide and 96 feet long. Because of a reflective property of an ellipse, a person standing at one focus can hear even a whisper spoken by a person standing at the other focus. (John Quincy Adams is said to have used this feature of the room to overhear conversations.) a. Find an equation of the ellipse b. How far apart are the two foci?. An irrigation project in Libya enables farmers to raise crops in the desert. Water from deep wells is pumped to sprinklers that rotate in circular patterns. Each circular field has an area of about,400,000 square yards. Write an equation that represents the boundary of one of the fields. Let (0,0) represent the center. 3. Most communications satellites have synchronous orbits, which mean they circle the earth at exactly the same speed as Earth is rotating. For a viewer on Earth, such a satellite appears to be stationary. Find an equation that represents the circular orbit of a satellite placed,40 miles above Earth. Let (0,0) represent the center. (The circumference of Earth is about 5,000 miles.) 4. LORAN (long distance radio navigation) uses synchronized pulses sent out by pairs of transmitting stations. By calculating the difference in the times of arrival of the pulses from two stations, the LORAN equipment locates the ship on a hyperbola. By dong the same thing with a second pair of stations, the ship s location will be the intersection of two hyperbolas. LORAN equipment has calculated a ship s position to be the point of intersection of the graphs of the following hyperbolas. Find the coordinates of the point of intersection. Draw an accurate xy 4 0 graph. x 5y In Australia, football (or rugby) is played on elliptical fields. The field can be a maximum of 170 yards wide and a maximum of 00 yards long. Let the center of the field of maximum size be represented by the point (0, 85). Write an equation of the ellipse that represents this field. The area of an ellipse is A ab. Find the area of the field. Draw an accurate graph. 6. You are opening a restaurant called the Treetop Restaurant. The menu cover has a tree on it. You are using a computer program to design the menu cover. The equation for the tree trunk is 100x 9y 36y Write this equation in standard from and y form and then draw an accurate graph. 7. The following is an equation of a comet s path. Tell what type of path the comet follows and draw an accurate graph of the comet s path. The sun is inside the path a distance of p units from the vertex, where p = (coefficient of the non-squared variable)/(4*coefficient of the squared term). Will this comet pass by the sun more than once? Explain how you know. 3550x 1400x 7100y

7 DESIGN PROJECT 1. You will create a design on your calculator. You must use all four conic sections at least once. The design should be aesthetically pleasing; a random hodgepodge of four conic sections will not earn full credit.. Print your design and program code using a GraphLink/TI-Connect and a computer. 3. Transfer your design to the teacher's calculator How to Program on Your Calculator Press the [PRGM] button on your calculator. Select [NEW] to create a new program. NAME: Type your last name. With any spaces remaining, type your first name. o Example: If I was creating the program, it would be SCOTTCHA 1 st line of Program: ClrDraw ( [ nd ] [PRGM] 1: ClrDraw ) This clears any pictures or other graphs already in your graphing window. nd line of Program: AxesOff ( [ nd ] [ZOOM] AxesOff ) This removes your axes from appearing when the picture is drawn. 3 rd line of Program: FnOff ( [VARS] [Y-VARS] 4: On/Off : FnOff ) Turns off any equations in the y menu 4 th line of Program: PlotsOff ( [ nd ] [Y=] 4: PlotsOff ) Turns off any Stat Plots.
