Integration Calculation Precautions
f x
• In the function ( ), only X can be used as a variable in expressions. Other variables (A
through Z excluding X,
that variable is applied during the calculation.

• Integration calculations can take a long time to complete.
• You cannot use a differential, quadratic differential, integration, , maximum/minimum value,
Solve, RndFix or log
• In the Math input/output mode, the tolerance value is fixed at 1
