# Fundamental rules for differentiation

Rule (I): Differentiation of a constant function is zero i.e., d/dx (c) = 0 Rule (II): Let f(x) be a differentiable function and let c be a constant. Then c.f(x) is also differentiable such that , This is the derivative of a constant times a function is the constant times the derivative of the function.
