For any real number c, treated as constant function, its derivative is zero and hence, we can write (1), (2) and (3) as follows : For the following, let u and v be functions of x, let n be an integer, and let a, c, and c be constants.

Actually, there exist infinitely many anti derivatives of each of these functions which
These are some of the most frequently encountered rules for differentiation and integration.
