Getting Started with the TI82 or TI83 Graphing Calculators
|
|
| 1. |
Press ON to turn calculator on. |
| 2. |
Press 2nd + to reset calculator. Move cursor down to 3. Press Enter. |
| 3. |
Scientific Calculator Keys are the Last six rows of keys. |
|
The upper four rows contain Graphing Keys. |
|
ENTER for "=" for subtraction, and () for negative numbers. |
| |
and () cannot be used interchangeably |
| 4. |
Enter the following: |
|
a. |
18 + 2 ENTER. See 18 + 2 = 20 |
| b. |
18 2 ENTER. Use the in the last column not () See 18 2 = 16 |
| c. |
18 + (2) ENTER. See 18 + (2) = 20 Use the () key. |
| ^ is the exponential key. Same as xy on a Scientific Calculator |
| 5. |
Enter the following: |
| |
  |
| 6. |
Put the following expressions in your grapher: |
| |
 |
| 7. |
Key in the following function. (Use the y= Menus) |
| |
 |
| Observe that the equal signs are shaded. |
| To remove a function, put the cursor on the line containing the function and press Clear. To keep a function, but do not want to graph it, place the cursor over the equal sign and press Enter. Note that the equal sign is no longer shaded. |
| 8. |
 |
|
Select Window. Enter the following: Xmin = 10, xmax=10, xscl = 1, ymin=10, ymax = 10, xscle= 1 Press graph. You should see the graph. You could have accomplish the above by selecting ZOOM and selecting #6. Note the graph appears right away. This is a much quicker way to graph using what is called the Standard Window. Look at the graph using different windows. Use ± 6 for x and y. Look at the graph in the window for x and y having values of 4 and 4, as well as + and 2. Which window do you like best? |
