Best ResponseYou've already chosen the best response.1Try and solve it yourselves, taking help from the step below. 1. differentiate the whole equation with respect to x, taking y as constant. name it 'U' 2. repeat step one but this time differentiate with respect to y taking x as constant. name it as 'V' 3. Dy/Dx =  (U/V)

Best ResponseYou've already chosen the best response.0You need to know a few rules: (y)'=y' (x)'=1 (fg)'=f'g+fg' (cos(x))'=sin(x) (sin(x))'=cos(x) (f(g(x)))'=g'(x) * f '(g(x))
