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

g(x) dx, etc.
• 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
fixed 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,
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,” 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
