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
expression inside of an integration calculation
term.
