| Method 1: Using d() function on Home screen |
| Steps |
Key Sequence |
Screens |
| 1. Set Up Differentiator |
Press F3, then ALPHA key, then = key (for nDeriv() |
 |
| 2. Type the Function |
|
 |
| 3. Input Variable |
Press comma, then the variable |
 |
| 4. Input Value for h |
Press comma, then 0.01 (or smaller) |
 |
| NOTE: The default value for h is 0.001 |
| 4. Execute Derivative |
Press ')', then ENTER |
 |
| |
| Method 2: Using graph of function |
| Steps |
Key Sequence |
Screens |
| 1. Input Function, Piecewise-Defined Function, or Parametric Equation. |
Press DIAMOND key, then F1 key (for Y=) |
 |
| |
Type the function |
 |
| 2. Graph |
Press DIAMOND key, then F3 key |
 |
| 3. Find Derivative |
Press F5 |
 |
| |
Press 6 (for Derivatives) |
 |
| |
Select appropriate derivative |
 |
| |
Type in value for x or trace function until you reach the value for x. |
 |
| Note: For a parametric equation: type in value for t or trace curve until you reach the value for t. |
| Note: In this case, we are finding the derivative of the function at x = 1. |
| |
Press ENTER |
 |
| Note: In this case, the derivative of the function at x = 1 is
dy/dx = –1. |
