CONIC PROJECT

Algebra 2H

DUE DATE: Wednesday May 2, 2018.

• This project is in place of a test.

• Projects are to be turned in at the beginning of 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 MADE.

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?

2. 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 2,400,000 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 22,240 miles above Earth. Let (0,0) represent the center. (The circumference of Earth is about 25,000 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 graph. [pic]

5. In Australia, football (or rugby) is played on elliptical fields. The field can be a maximum of 170 yards wide and a maximum of 200 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 [pic]. 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 [pic]. Write this equation in standard from and [pic] 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.

Conics Word Problems

HAWAII Hawaii joined the US in 1959, making it the 50th and only state not to lie on the mainland of North America. Hawaii is made up of a chain of 132 islands located in the North Pacific. The chain of islands covers a distance of 1523 miles with eight main islands at the southeastern end of the chain.

Assume Honolulu is [pic] and each interval represents 40 miles.

DESIGN PROJECT

g. You will create a design on your calculator. You must use all four conic sections at least once. The design should be of something. "Just pretty designs" or a random hodgepodge of four conic sections will not earn full credit.

h. Print your design and program code using a GraphLink/TI-Connect and a computer.

i. 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

• 1st line of Program: ClrDraw ( [2nd] [PRGM] 1: ClrDraw )

This clears any pictures or other graphs already in your graphing window.

• 2nd line of Program: AxesOff ( [2nd] [ZOOM] AxesOff )

This removes your axes from appearing when the picture is drawn.

• 3rd line of Program: FnOff ( [VARS] [Y-VARS] 4: On/Off 2: FnOff )

Turns off any equations in the [pic] menu

• 4th line of Program: PlotsOff ( [2nd] [Y=] 4: PlotsOff )

Turns off any Stat Plots. OMIT this line if your graph uses the stat plots

• Set your window. Type the number you want for the minimum and maximum values for x and y

Should be of the form:

-23.5 ( xmin

23.5 ( xmax

-15.5 ( ymin

15.5 ( ymax

xmin, xmax, ymin, and ymax can be found by pressing [VARS] 1: Window

Note that the "(" is the arrow found by pressing the [STO] button on the calculator

You may use any window you want, but you should have the x : y ratio close to 3 : 2

• Enter equations by pressing [2nd] [PRGM] 6: DrawF(

Restrict domains by pressing the divide button and then using the TEST Menu ([2nd] [MATH])

For example… :DrawF[pic]

• Use [CLEAR] to delete an entire line

• Use [2nd] [DEL] to insert a blank line

• You can shade if desired by pressing [2nd] [PRGM] 7: Shade

:Shade(F1, F2, x1, x2)

F1: Bottom function where shading begins

F2: Top function where shading ends

x1, x2: Starting and ending domain values to shade

I have found that this does usually does not work very well

Printing the Graph

• Run the program and get the image on your calculator

• Connect your calculator to a computer using a Link Cable

• Open TI-Connect

• Choose Screenshot from the main menu

• Take a screenshot of the calculator to print

• IMAGE ( RESIZE ( 300%

• Print the image

Printing the Code

• You may not screen capture the code from the calculator; it must be neatly typed

• You will need to type your computer code into a word processor and print it
