Lolz...didn't even neded to substitute.

waste of your time.

Yah the substitution was kinda silly :) If you do a substitution, don't forget to change the limits of integration also.

And there's no du at the back of the integral

So there's no solution

You can't continue on integrating that without respect of anything.

Ops, sorry forgot about the du.. It is in respect to du

What are you integrating with respect to? You integrating with respect to zero?
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.0
Okay. Now you can integrate it. Just separate the numerator.

Azteck Group TitleBest ResponseYou've already chosen the best response.0
And you can continue integrating per usual.

\[\int\limits_{}^{}\frac{ 1 }{ \sqrt{u} }du\int\limits_{}^{}1du\]\[\int\limits_{}^{}u^{\frac{ 1 }{ 2 }}duu\]\[2u^{\frac{ 1 }{ 2 }}u\]Then just plug in the limit from 0 to 4

My only real problem is finding the antiderivative

Azteck Group TitleBest ResponseYou've already chosen the best response.0
Antidifferentiating is just differentiating in reverse. Try and use reverse psychology when integrating if you can.

\[\large \frac{1\sqrt u}{\sqrt u} \qquad = \qquad \frac{1}{\sqrt u}\frac{\sqrt u}{\sqrt u} \qquad = \qquad u^{1/2}1\] Yah you just apply the `Power Rule for Integration`! :D
