14 Solving and Integrating Programs Solving a Program In chapter 7 you saw how you can enter an equation - it's added to the equation list - and then solve it for any variable. You can also enter a program that calculates a function, and then solve it for any variable. This is especially useful if the equation you're solving changes for certain conditions or if it requires repeated calculations. To solve a programmed function: 1. Enter a program that defines the function. (See "To write a program for SOLVE" below.) 2. Select the program to solve: press | W label. (You can skip this step if you're re-solving the same program.) 3. Solve for the unknown variable: press variable. Notice that FN= is required if you're solving a programmed function, but not if you're solving an equation from the equation list. To halt a calculation, press or g. The current best estimate of the root is in the unknown variable; use | to view it without disturbing the stack. To resume the calculation, press g. To write a program for SOLVE: The program can use equations and ALG or RPN operations - in whatever combination is most convenient. 1. Begin the program with a label. This label identifies the function that you want SOLVE to evaluate (/label). Solving and Integrating Programs 14-1
