# 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 the tolerance (tol) value and the
closing parenthesis can be omitted. If you omit
tolerance (tol) value, the calculator automati-
cally uses a value for tol as 1
E
-10.
# Specify tolerance (tol) value of 1
E
-14 or less.
An error (Iteration ERROR) occurs whenever
no solution that satisfies the tolerance value
can be obtained.
# Discontinuous points or sections with drastic
fluctuation can adversely affect precision or
even cause an error.
