Integration Calculation
Your calculator performs integration using Gauss-Kronrod integration for approximation. The
calculator uses the following function for integration.
∫ (
A Syntax and Input
∫ (
f
(
x
),
a
,
b
,
tol
)
f
(
x
): Function of
x
(Input the function used by variable X.)
• All variables other than X are viewed as constants.
a
:
Lower limit of region of integration
b
:
Upper limit of region of integration
tol
: Error tolerance range (Can be input only when linear display is being used.)
• This parameter can be omitted. In that case, a tolerance of 1 × 10
–5
is used.
Example:
∫ (ln(
x
), 1,
e
) = 1 (
tol
value not input)
