Integration Calculation Precautions

• In the function

f

(

x

), only X can be used as a variable in expressions. Other variables (A

through Z excluding X,

r

,

) are treated as constants, and the value currently assigned to

that variable is applied during the calculation.

• Input of “

tol

” and closing parenthesis can be omitted. If you omit “

tol

,” the calculator

automatically uses a default value of 1

E

–5.

• 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

E

–5 and cannot be changed.

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
