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

y = x

+ 4x

+ x – 6, with a tolerance of “tol” = 1E – 5

Input the function f(x).

AK4(CALC)b(d/dx)vMd+evx+v-g,

Input point x = a for which you want to determine the derivative.

Input the tolerance value.

bE-f)

#In the function f(x), only X can be used as a

variable in expressions. Other variables (A

through Z, r,

) 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.
