k Integration Calculations [OPTN]-[CALC]-[

∫

dx]

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

values in the formula shown below.

K4(CALC)d (

∫

dx) f(x) , a , b , tol )

∫

( f(x), a, b, tol) ⇒

∫

f(x)dx

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

integral values from a through b for the function y = f (x) where a < x < b, and f (x) > 0. This

in effect calculates the surface area of the shaded area in the illustration.

f (x)dx is calculated

(a: start point, b: end point, tol: tolerance)

#If f (x) < 0 where a a < x < b, the surface area

calculation produces negative values (surface

area × – 1).
