Best ResponseYou've already chosen the best response.1hi water , have you heard of exp x = \[x + x ^{2}/2! + x ^{3}/3! + x ^{4}/4!.........\]

Best ResponseYou've already chosen the best response.1if you know this then u can substitute exp x by the above and further see if its solvable !

Best ResponseYou've already chosen the best response.0For convenience, 1/x is the first function.. e^x as second function.. \[\int\limits_{}^{}(\frac{1}{x}).e^x.dx = \frac{1}{x}.e^x  \int\limits_{}^{}(\frac{1}{x^2}.e^x).dx\] \[= \frac{e^x}{x} +\int\limits_{}^{} \frac{e^x}{x^2}.dx\] But now x will move on increasing like x^3, x^4 etc etc..

Best ResponseYou've already chosen the best response.0yeah now you have to do integration of (e^x)/x^2 right?

Best ResponseYou've already chosen the best response.1yes however switch the u and dv to go back and then add them and divide by 2

Best ResponseYou've already chosen the best response.0Right but that will lead to x^3 then this process continues..

Best ResponseYou've already chosen the best response.2there was a little mistake in my answer \[\int\limits \frac{e^x}{x}dx=\int\limits \frac{1}{x} \sum_{n=0}^{\infty} \frac{x^n}{n!}dx=\sum_{n=0}^{\infty} \int\limits \frac{x^{n1}}{n!} dx=\ln x+\sum_{n=1}^{\infty} \frac{x^{n}}{n.n!}\]
