Hey friends !

I cannot find the way of solving that exercise....
I've tried so many methods but I'm desperate....

I will be grateful for it to be solved !

Thanks !!

1.

You should have no trouble integrating

.

and you use the substitution

2.

Now use partial fractions.

I made it to be the first integration (frst file).... after that I've continued and made it to be something with ln and an integral (scnd file)..
And now I do not know how to solve only the scnd file's integration....

Thanks !

Youre almost there.

I know how to solve the first integration you post (mult by 1/2) because the numerator is a derivative of the denominator--> solve that is ln with something , and I've reached also to the second integral (who mult by 3) but I've stuck on it

Use the substitution

Ok I solved the second exercise but.... for the first exercise which u wrote:

I did not make it to be a simple integration after the substitution..... thats because I became entangled with it... can u show me the solution ?

Thanks !
