Calculate the derivatives of any mathematical functions
You just have to set the function and the derivative will appear once to have clicked the right button.
The input has a helper for mathematical functions has cos(x) or sin(x).
You can set the degree of derivatives you want to set.
The derivative of y with respect to x is defined as the change in y over the change in x, as the distance between x0 and x1 becomes infinitely small
A perfect application if you are a student or a scientist.
