18TXTED.DOC TI-89/TI-92 Plus: Text Editor (English) Susan Gullord Revised: 02/23/01 1:15 PM Printed: 02/23/01 2:18 PM Page 331 of 18
General Steps For Detailed Information
1. Connect the
TI-89 / TI-92 Plus to your
computer via the TI-GRAPH
LINK cable.
Refer to the manual that came
with your TI-GRAPH LINK.
2. Use the TI-GRAPH LINK
software to get the lab
report from the calculator,
and then print the report.
A
ssume you have stored:
¦ A function as y1(x)
(specify y1, not y1(x)).
¦ A graph picture as pic1.
¦ Applicable information in
variables der and sol.
When you print the lab report,
the contents of the print
objects are printed in place of
their variable names.
My assignment was to study the function:
.1*x^3ì.5*x+3
The three parts were:
1. Graph the function.
2. Find its derivative.
.3*x^2ì.5
3. Look for critical points.
x=1.29099 or x=ì1.29099
In cases where a graph picture cannot fit on the current page, the
entire picture is shifted to the top of the next page.
Printing the Report
Example
Note: To store the
derivative to variable der,
enter:
d(y1(x),x)!der
Note: To store the
derivative’s critical points to
variable sol, enter:
solve(der=0,x)!sol
