Solving and Integrating Programs 15-7
Integrating a Program
In chapter 8 you saw how you can enter an equation (or expression) — it's added
to the list of equations — and then integrate it with respect to any variable. You can
also enter a program that calculates a function, and then integrate it with respect to
any variable. This is especially useful if the function you're integrating changes for
certain conditions or if it requires repeated calculations.
To integrate a programmed function:
1. Enter a program that defines the integrand's function. (See "To write a program
for
∫ FN" below.)
