# Online derivative calculator

*Derivative of a function* is the limit of the infinitesimal change in the function with respect to infinitesimal change in the variable, provided that the last tends to zero.

To find derivative of some function you'd apply basic differentiation rules or use our online step by step *derivative calculator*.
It capable to calculate second, third and other higher order derivatives. You can also choose differentiation variable and calculate
partial derivatives in case of multivariable functions.

There are several ways to input your expression into calculator. The first one is simple input, which means that you input your expression using keyboard. To make you expression input correct you'd learn math expressions input rules. The second one is advanced input, which means that you input your expression by left mouse click on buttons as in calculator. Check math panel input rules to learn how input expression by advanced input.
