II. Menu Keys - Keys that offer choices

Several of these functions can also be found in the graph MATH menu when you have a function graphed.

1. evalF (expression, variable, value)

Evaluates an expression for a given value.
Press .

2. nDer (expression, variable, value)

Approximates the numerical value of a derivative.
Press .

3. der1 (expression, variable, value)

Approximates the numerical value of the first derivative.
Press .

4. der2 (expression, variable, value)

Approximates the numerical value of the second derivative.
Press
.

5. fnInt (expression, variable, lower bound, upper bound)

Approximates a definite integral.
Press .

6. fMin (expression, variable, lower bound, upper bound)
7. fMax (expression, variable, lower bound, upper bound)
