d1f: First Derivative

In JackStat/CompPack: Collection of Computational Statistic Tools

Description

The first derivative of a function evaluated at point(s) x.

Differentiation is a method to compute the rate at which the dependent output (f(x)) changes with respect to the change the independent input (x). The first derrivative can be used to obtain an exact value for the slope of the tangent line, at the point where the derivative was evaluated.

Usage

  d1f(f, x)

Arguments

f	The function that you want to take the derivative of
x	The point or vector of points where the derivative will be evaluated
