Graphing Calculator Programs
These programs allow students to use TI83/84 Plus calculators
to investigate the mathematics they are learning.
Please be sure to download the appropriate file
for your platform. After downloading, consult your TI83/84 Plus user's
manual for instructions on how to transfer the file to your calculator
using a TI GraphLink cable and software. If you need additional assistance,
please access the Texas
Instruments Calculator site.
PC users can directly download the file to
the desktop.
Macintosh users should download the associated *.sea file to
the desktop and doubleclick to Unstuff it.
Chapter 1 (page 10)
Description: plots points in a relation
Special Instructions: The program will prompt you to enter the
x and y values you wish to graph. It will then ask if you wish to
graph more points or to quit.
PC  MAC
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 xcoordinate that lies on the graph of the function and
then will calculate whether the function is odd, even, or neither.
PC  MAC
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.
PC  MAC
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.
PC  MAC
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.
PC  MAC
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 3560 minutes to run.
PC  MAC
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.
PC  MAC
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.
