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,” 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 or Solve calculation expression inside of
an integration calculation term.
