TI 84 Color Programs
For this blog entry, I used TI Connect CE to transfer the programs and get screen shots. It is sweet! TI Connect CE works with the TI-84 Plus family (Monochrome, C Silver Edition, and the upcoming CE (review coming soon!)). You can edit programs and transfer them. The interface is a lot nicer, and you can drag and drop programs and data files.
This blog will feature some of the color functions and commands of the TI 84 Plus C Silver Edition (and the upcoming TI 84 Plus CE).
|CIRCLE4 in Progress|
CIRCLE4: Circle Draw and Update Program
* Press 1, 2, 3, and 4 to change the color of the circles. The colors cycle through black, blue, red, and green.
* Since a list is used, we must use the numeric color identifiers: 12 for black, 10 for blue, 11 for red, and 14 for Green. (see table below for full reference)
* Database is stored and recalled to preserve the current database (0).
Numeric Color Identifiers:
18: light blue
21: light gray
22: medium gray
24: dark gray
ARC84C: Arc Length
Find the Arc Length of function Y1. Once the arc length is calculated, the function is plotted in black and the arc length is plotted in red.
FnOff :Func:FnOn 1
Input "Y₁, USE STRINGS:",Y₁
Disp "ARC LENGTH=",L
Y1 = cos(X)*e^X from X = 1 to 2. Arc Length = 4.7031139029…
Y1 = -2X^2 + 4X + 1 rom X = -2 to 2. Arc Length = 20.7833…
AREABTWN: Area Between Curves
This calculates the area between two curves, Y1 and Y2. This program works best if you can set the graph screen to where the curves intersect at only two points. The program first searches for two intersections, one from the left side of the graph screen (Xmin) and one from the right (Xmax). After the area is calculated, both curves are graphed and the area between curves are shaded. Function and Radian modes are used.
FnOn 1:FnOn 2
Disp "NO SOLUTION":Stop
Disp "PRESS ENTER TO GRAPH"
The Standard Window is used. Xmin = -10, Xmax = 10, Ymin = -10, Ymax = 10
Y1 = -2X^2 + 4X + 1, Y2 = X^2. Area = 2.734721…
Y1 = 1.2X + .63, Y2 = -X^2 + 5X + 1. Area = 10.58676675…
I plan to accomplish the same programs for the Casio Prizm soon. Eddie
