# Math Help - Derivative

1. ## Derivative

In maths terms explain derivative

2. ## Re: Derivative

Given a function, f(x), its derivative, at x= a, is $\lim_{h\to 0}\frac{f(a+h)- f(a)}{h}$ provided that limit exists. If that limit does NOT exist, f is not differentiable and x= a and the derivative does not exist.

3. ## Re: Derivative

Derivative is an term that shows rate of change of somthing at any point so we can say derivaive are all about change. Example : f(x) = x^2
x f(x)
0 0
0.5 0.25
As x increases, so does f(x)

4. ## Re: Derivative

The derivative is a measure of how a function changes as its input changes. Loosely speaking, a derivative can be thought of as how much one quantity is changing in response to changes in some other quantity; for example, the derivative of the position of a moving object with respect to time is the object's instantaneous velocity.
