You want to apply product rule for that one

anonymous · Answer

This is finding the Differential though, it is more than just the product rule

allank · Answer

Whoops, read differentiate

allank · Answer

From some quick reading, http://en.wikipedia.org/wiki/Differential_of_a_function It appears that the differential of a function f(x) is $$dy = f'(x)dx $$ where $$f'(x) $$ is the derivative of f(x) with respect to x. So it's basically finding dy/dx and making dy the subject of the equation.
