f(x)
# In the function , only X can be used as a
variable in expressions. Other variables (A
r
through Z, , " ) 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
