Presented online application calculates the analytic formula of the first derivative of a given function. Derivative represents a rate of change of a function with respect to an independent variable (to learn more go to this page). This app enables to differentiate a function that depends on more than one independent variable by considering these variables separatelly. 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 this case (called here a multi-parametric case), all 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:
