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.

⇒
∫

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.

# If f (x) < 0 where a a < x < b, the surface area
calculation produces negative values (surface
area × – 1).
