Derivative

Creates a new function representing the derivative of the expression/variable that was passed into it.

1 \derivative[<action>]{<variable>}{<expression>}{<free_variable>}

action, variable and expression are identical to the input of a \function command.
free_variable defines the free variable in the given expression.
$$f_1 = 4x^3 + 2 \cdot 3x^2$$ is the output of
1 2 3 4 5 6 \derivative{f_1}{x^4 + 2*x^3}{x} % and is equal to the following \function{f}{x^4 + 2*x^3} \derivative{f_1}{f}{x}
