The second derivative of the function f is the function f '' = (f ' )'. It is the derivative of the derivative.
There are a number of ways to write the second derivative of y = f(x) . These include
The derivative of f '' is denoted f ''' and is called the third derivative of f. It is also written as f (3) . The derivative of f (3) is f (4) , the fourth derivative of f. In general:
The derivative of the nth derivative is the n-plus-first derivative: f (n+1) = ( f (n) )'
The parentheses in the exponent distinguish the nth derivative f (n) from the nth power f n of f.
