3-5 Integration Calculations

To perform integration calculations, first display the function analysis menu, and then
input the values shown in the formula below.
P.64
Integration calculations are performed by applying Simpson's Rule for the
tion you input. This method requires that the number divisions be defined as
where the value of

As shown in the illustration above, integration calculations are performed by calcu-
lating integral values from
