Description: Returns the derivative of a function of x at a specified number. It is a numerical evaluation of the derivative of f(x) at that number.
Syntax: derivative(f(x), number)
f(x) is an equation in terms of x.
number is the number at which the function is evaluated.
Remarks:
The function must evaluate at that number; otherwise an error is returned.
All parameter values can include:
Numerical values
Standard operands (+, -, *, /)
Predefined mathematical functions (exp, log, sin, etc.)
References to any Synthesis Workbooks
Example:
