How do you calculate the derivative function?
The TI-84 Plus uses an algorithm to compute the derivative, given by the formula: nDeriv(ƒ(t),t,x,h) = [ƒ(x + h) − ƒ(x − h)]/(2h), where ƒ(t) is the function, t is the respective variable, x is the point at which to evaluate, and h is the step size (default value if omitted is .001).
What is the formula for derivatives?

The derivative of a function f at the point x is defined as the limit of a difference quotient: f0(x) = lim h→0 f(x+h)−f(x) h In other words, the difference quotient f(x+h)−f(x) h is an approximation of the derivative f0(x), and this approximation gets better as h gets smaller.
