Use Formula Editor Options
There are several options available to you as you create formulas. The following sections discuss each of
these options.
Calculate Derivatives
The JMP Formula Editor can find and display the derivative of a function. The derivative is found with
respect to the function argument (a single variable name) you highlight. Therefore, in order to differentiate
with respect to x, x must be one of the arguments in the expression. The red triangle menu found above the
keypad contains the Derivative command.
To calculate a derivative:
1. Enter a function.
2. Highlight a variable.
3. Select Derivative from the menu. Figure 7.6 shows the completion of these steps.

Simplify Complex Formulas
When the Formula Editor contains a complex formula, JMP can simplify it using various algebraic rules. It
can find constant expressions, distribute multiplication over addition, combine terms, and more.
To simplify complex formulas:
1. Select a portion or all of the formula.
2. Click the red triangle menu above the keypad.
3. Select Simplify from the menu that appears, as shown in Figure 7.7.
