Integration Calculation

Your calculator performs integration using Gauss-Kronrod integration for approximation. The
calculator uses the following function for integration.

f x
( ): Function of
• 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
