# In the function , 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
