You need to rewrite them as and use integration by parts, so choose and , then

,

where is the differential of and is the antiderivative of .

Feel free to ask, if anything I just wrote need explanation :) - Dec 11th 2012, 11:41 AMasilvester635Re: Integration help
yah it should be ^-1/2 but i made a mistake on putting ^4

So i got this

= (2)2(x + 4)^1/2

is that right???? - Dec 11th 2012, 11:48 AMskeeterRe: Integration help

can anyone check if i got it right.

i got...

= 2(x + 4)^1/2 - 7(x + 4)^-1/2 + c - Dec 13th 2012, 04:17 PMskeeterRe: Integration help

We know that

More compactly:

For Let and

where is the antiderivative of and is the derivative of
