Problem 1. Evaluate  

Solution.  By substitution x = at,

Problem 2. Evaluate  

Solution.  By substitution x = at,

Problem 3.  Prove the following formula:

.

Proof. The formula can be verified by differentiation. We have only to check whether the derivative of the function  equals the integrand.

That is true and hence the formula.
