Evalute the following integrals

Hi

Evalute the following integers

 

[Fightfish]

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!

Hi

all is correct instead of substitution ??

Your substitution is fine.

What is u when $\ x=\sqrt{\ln(\pi)}\,,\$ 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.

thanks so much ...
