Question

help me pleasee :(

Answer 1

Sure

Answer 2

how to evaluate
\[\int\limits_{}^{}(1+e^{x})^{2}\div e^{x} dx\]
and
\[\int\limits_{}^{}e^{1/x}\div x^{2} dx\]

I try to do with substitution, but it's not as perfect as I want :(

Answer 3

Think about squaring the term first.
Then divide by the e^x..
Then take the integral of the individual parts...
...and you are good to go.
