Function derivatives examples

Know how and good skills in functions derivatives calculation is very important in science and engineering. On this website you can find plenty of examples about functions derivatives which are solved step by step. We often use functions derivatives to find maxium or minimum value of function.

Basic functions derivatives

Derivatives of basic functions.

We are lucky because we don't have to designate all derivatives of functions. Mathematicians had designated plenty of basic derivatives of functions. Most of functions which you will meet are complex of basic functions. Below are placed basic functions derivatives and some basic theorems about function derivatives.
