    Re: Evalute the following integers

    You mean "integrals". There's a HUGE difference between integers and integrals!
    Plus, where's the problem you're facing with these qns and your attempts?

    Remember to change your integration limits after the substitution!

    Re: Evalute the following integers

    Your substitution is fine.

    What is u when [itex]\ x=\sqrt{\ln(\pi)}\,,\ [/itex] and when x = 0. Those are your limits for the integral in u .

    Otherwise, use substitution to find the anti-derivative in terms of u, then convert that anti-derivative back to x and evaluate the definite integral using the limits for x.
