# Steps to find the derivative of a function

### The derivative using the limit definition

The derivative using the limit definition Definition The derivative of the function $displaystyle f$ at the point a is the limit when $displaystyle hto 0$ of the function, if this limit exists. We label it f´(a) and $displaystyle f'(a)=underset{{hto 0}}{mathop{{lim }}},frac{{f(a+h)-f(a)}}{h}$ When the function$displaystyle f$ is derivative on the point \$ displaystyle […]
