u Application of Integration Calculation
•Integrals can be used in addition, subtraction, multiplication and division.

•Integration results can be used in addition, subtraction, multiplication and division, in
functions.

Numerical Calculations
#In the function f(x), only X can be used as a
variable in expressions. Other variables (A
through Z,
r,
θ
) 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,” t he 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 or Solve calculation expression inside of
an integration calculation term.
