Theorem.  If  f (x)  is continuous on a closed interval  [a, b] and  f (x)  is a primitive of  f (x) on  [a, b]  then

.


Proof.  Set  x = a  to find the constant  C:

.

Hence,

.

Setting  x = b, get the desired result:

.


The Fundamental Theorems of Calculus states interrelations between definite and indefinite integrals.
