Presented online application transforms a function into its derivative. Derivative represents a rate of change of a function with respect to an independent variable. This app enables to differentiate a function that depends on more than one independent variable by considering these variables individually. To do so, one must declare a name of independent variable with respect to which a given function is differentiated. During differentiation, the rest of variables is kept constant. In such a case (called here a multi-parametric case), a number of remaining independent variables must be set by the user.
Numerical differentiation can support analytic solution. Obtained results can be depicted in plots.
The first derivative reads:
