Chapter 3 (page 133)
Description: determines whether a function is even, odd, or neither
Special Instructions: Enter the function you are testing as Y1 in the Y= menu before running the program. The program will prompt you to enter an x-coordinate that lies on the graph of the function and then will calculate whether the function is odd, even, or neither.

Chapter 4 (page 226)
Description: computes the value of a function
Special Instructions: Enter the function you are testing as Y1 in the Y= menu before running the program. The program automatically repeats itself until you quit.

Chapter 5 (page 331)
Description: determines the area of a triangle, given the lengths of all sides of the triangle
Special Instructions: The program will prompt you to enter the measure of each side of the triangle.
PC - MAC

Chapter 5 (page 333)
Description: determines the lengths of the sides and the angle measures of a triangle, given the coordinates of the vertices of the triangle
Special Instructions: Make sure the calculator is set in DEGREE mode. The program will prompt you to enter each vertex. Enter each coordinate separately followed by pressing ENTER.

Chapter 7 (page 470)
Description: computes the distance from a point to a line
Special Instructions: Make sure the equation of the line is written in standard form before beginning the program. Enter the information from each prompt in the program.

Chapter 8 (page 512)
Description: determines the components of the cross product of two vectors
Special Instructions: The program will ask you to identify the two vectors as (A, B, C) and (X, Y, Z). Enter each coordinate separately followed by ENTER. The result will appear as three values in order of their appearance in the ordered triple.

Chapter 9 (page 582)
Description: performs complex iteration
Special Instructions: Make sure the calculator is in complex
(a + bi) mode before beginning the program. When entering the number, enter it in a + bi form.
PC - MAC

Chapter 9 (page 604)
Description: draws Julia sets
Special Instructions: Make sure the calculator is in complex
(a + bi) mode. Set the calculator window for [0, 100] scl:1 by
[0, 100] scl:1. CX and CY correspond to a and b, respectively, in a + bi. Select values from -1.5 to 1 for CX and CY to make the program run more efficiently. This program takes 35-60 minutes to run.

Chapter 10 (page 620)
Description: determines the distance and midpoint between two points
Special Instructions: The two points are entered as (X1, Y1) and (X2, Y2). Each coordinate is entered separately followed by ENTER. The coordinates of the midpoint are displayed on two separate lines.
PC - MAC

Chapter 10 (page 628)
Description: determines the radius and the coordinates of the center of a circle from an equation written in general form
Special Instructions: Write the equation of the circle in standard form before beginning the program. Enter the values of D, E, and F when prompted.

Chapter 11 (page 710)
Description: calculates loan payments
Special Instructions: Enter each value when prompted. Do not use commas when entering the numbers. APR means annual percentage rate.
PC - MAC

Chapter 12 (page 780)
Description: calculates the value of the nth term of a continued fraction sequence
Special Instructions: Each term of this sequence equals the sum of A and the reciprocal of the previous term. When prompted, enter any value for A, the initial term of the sequence.
PC - MAC

Chapter 14 (page 961)
Description: uses rectangles to approximate the area under a curve
Special Instructions: The program approximates the area between the graphs of two functions by dividing the region into rectangles. Store the two functions as Y1 and Y2 in the Y= list before beginning the program. It is a good idea to look at the graphs of the two functions to help you determine the lower and upper bounds from which the rectangles are to be made.
