Higher Derivatives & Partial Differentiation Raymund T. de la Cruz MAEd - Mathematics
Higher Derivatives If y = f (x) is differentiable, its derivative y′ is also called the first derivative of f. If y′ is differentiable, its derivative is called the second derivative of f. If this second derivative is differentiable, then its derivative is called the third derivative of f, and so on. Notation First Derivative Second Derivative Third Derivative nth Derivative
