Notes On Second Order Derivatives - CBSE Class 12 Maths
Consider a function y = f(x) (the derivative of y with respect to x) dy/dx = f '(x) d/dx(dy/dx) is called the second order derivative of y w.r.t. x. d/dx(dy/dx) = d2y/dx2 or D2y or y'' or y2 d/dx(f '(x)) = f '' (x) Third order derivative of y w.r.t. x = d3y/dx3 Fourth order derivative of y w.r.t. x = d4y/dx4
