u u u u u To perform an integration calculation

Example

To perform the integration calculation for the function shown

below, with a tolerance of "tol" = 1

(2x

f (x)

Input the function

AK4(CALC)4(

Input the start point and end point.

b,f,

Input the tolerance value.

• In the function

variables (A through Z,

assigned to that variable is applied during the calculation.

• Input of "tol" in Gauss-Kronrod Rule, "

parenthesis with both rules can be omitted. If you omit "tol", the calculator

automatically uses a value of 1

cally selects the most appropriate value.

• Integration calculations can take a long time to complete.
