DEFINITION
If the derivative of a function (the first derivative, f'(x)) is differentiated, a new function is obtained called the second derivative, f''(x).
If this function is differentiated again, a third derivative, f'''(x), is obtained.
If the third derivative, f'''(x), is differentiated, the fourth derivative, is obtained. This process can continue and these resultant functions are referred to as higher order derivatives.
