The derivative of a function f(x) is written f'(x) and describes the rate of change of f(x). It is equal to slope of the line connecting (x,f(x)) and (x+h,f(x+h)) as h approaches 0. Evaluating f'(x) at x_0 gives the slope of the line tangent to f(x) at x_0.

Drag the dot! Change h! In the graph above: are there any points that makes defining the derivative difficult? The derivative as a function. You can extend the definition of the derivative at a point to a definition concerning all points (all points where the derivative is defined, i.e. where the limit exists); if doing so you get a new function \(f'(x)\) defined like this:

The slope of the tangent line to the graph of a function at a point is called the derivative of the function at that point. The formal definition of derivative ...

The Derivative at a Point. The slope of a function at a particular point can be calculated exactly using the limit of a difference quotient.

The derivative of a function f(x) at a point x=a can be defined as a limit. It is commonly interpreted as instantaneous rate of change.

The derivative of a function is one of the basic concepts of mathematics. Together with the integral, derivative occupies a central place in calculus. The process of finding the derivative is called differentiation.The inverse operation for differentiation is called integration.. The derivative of a function at some point characterizes the rate of change of the function at this point.

Defintion of The Derivative

Subsection 1.3.1 The Derivative of a Function at a Point. Just as we defined instantaneous velocity in terms of average velocity, we now define the instantaneous rate of change of a function at a point in terms of the average rate of change of …
