The partial derivative function

Parent Previous Next

MathGraph32 is able to calculate the partial formal derivative function of a real function of two or three variables.


It is created via icon of the calculations expandable bar (third from the bottom).


A dialog box appears displaying all available functions.


Select the function, specify a name for the derivative and choose the variable of derivation.


To be noted : It is the result of a formal calculus but the formula of the derivative is not available to the user.
