Second derivative

In physics and mathematics (particularly in differential calculus), the second derivative is the derivative of the derivative of a function, say . The second derivative has many real-life applications, especially in the study of mathematical optimization and acceleration. Second derivatives can be notated in several ways, some of which are

,    or  

Other notations are used, but the above two are the most commonly used.

 Power Rule for Finding the Second Derivative
