3-4 Integration Calculations

To perform integration calculations, first display the function analysis menu and

then input the values in one of the formulas shown below.

Gauss-Kronrod Rule

Simpson's Rule

As shown in the illustration above, integration calculations are performed by

calculating integral values from

f (x) > 0

illustration.

k Changing Integration Calculation Methods

This calculator can use either Gauss-Kronrod Rule or Simpson's Rule to perform

P.6

integration calculations. To select a method, display the set up screen and select

either "Gaus" (for Gauss-Kronrod Rule) or "Simp" (for Simpson's Rule) for the

Integration item.

All of the explanations in this manual use Gauss-Kronrod Rule.
