Integration Calculation Precautions

• In the function
through Z excluding X,
that variable is applied during the calculation.
tol
• Input of " " and closing parenthesis can be omitted. If you omit "
automatically uses a default value of 1
• Integration calculations can take a long time to complete.
• You cannot use a first derivative, second derivative, integration, Σ, maximum/minimum value,
Solve or RndFix calculation expression inside of an integration calculation term.
• In the Math input/output mode, the tolerance value is fixed at 1
k Σ Calculations
To perform Σ calculations, first display the function analysis menu, and then input the values
using the syntax below.

Σ Calculation Precautions
• The value of the specified variable changes during a Σ calculation. Be sure to keep separate
written records of the specified variable values you might need later before you perform the
calculation.
• You can use only one variable in the function for input sequence
