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) ⇒
∫
a
b
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.

(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).
