# Differentiation – Rules 2

Differentiation – Rules 2 Derivative of Composite Function: If f(u) is differentiable at the point u = g(x) and g(x) is differentiable at x, then the composite function (fog)(x) = f{g(x)} is differentiable at x and (fog)’(x) = f’{g(x)}. g’(x). Relation between dy/dx and dx/dy: If the inverse functions f and g are defined by Read more about Differentiation – Rules 2[…]
