Example To determine the derivative at point x = 3 for the function
y = x
3
+ 4x

+ x – 6, with a tolerance of “tol” = 1E – 5
Input the function f(x).

Input point x = a for which you want to determine the derivative.
d,
Input the tolerance value.

#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.
