The derivative is an important tool in calculus that represents an infinitesimal change in a function with respect to one of its variables. Given a function f(x), there are many ways to denote the derivative of f with respect to x. The most common ways are (df)/dx and f'(x). When a derivative is taken n times, the notation (d^n f)/(dx^n) or f^n(x) is used. These are called higher order derivatives.
