Question

Integration Help plzz!!

Answer 1

\[\int\limits_{?}^{?}\frac{ (e^x(1+x))\ }{ (1+\cos(e^x.x))^2 } dt\]

Answer 2

plug in
\(u = x e^x\)

what is du=... ?

Answer 3

wait!
Ther is no + 1 in the denominator

Answer 4

\[e^x(1+x)\]

Answer 5

then its even more easier :)

Answer 6

you mean

du = e^x(1+x) dx
right ?

Answer 7

Lulz!!
PLzz type in the solution i worked more than 2 hours on it.
Yeah. du=e^x(1+x)dx

Answer 8

thats your numerator!

Answer 9

so you now have

\(\Large \int \dfrac{du}{\cos^2 u}\)
right ?

Answer 10

tan (e^x.x)+ c got the anwser

Answer 11

It was easy!
i wasted my life sad. :(
Thank you man.

Answer 12

very good!
you're learning! it happens :)

Answer 13
