u Application of Integration Calculation
• Integrals can be used in addition, subtraction, multiplication or division.
• Integration results can be used in addition, subtraction, multiplication or division, in
functions.
• Functions can be used in any of the terms (
f ( x ), a , b , tol) of an integral.

Numerical Calculations
# In the Math input mode, the tolerance value is
fi xed at 1
E-5 and cannot be changed.
# In the function
f ( x ), only X can be used as
a variable in expressions. Other variables
(A through Z excluding X,
r , Ƨ) 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 differential, quadratic
differential, integration, Σ , maximum/minimum
value, Solve, RndFix or log ab calculation
expression inside of an integration calculation
term.
