Best ResponseYou've already chosen the best response.0Hmm can't do the integral but the aproximation I do get to 1.

Best ResponseYou've already chosen the best response.0Yeah one more which i was doing was Integral (x^2/x^2+1) and i got x arctanx by trig sub.

Best ResponseYou've already chosen the best response.1thats correct....and can be done without substitution...

Best ResponseYou've already chosen the best response.1if u can use this integral as standard int 1/(1+x^2) dx = arctan x +c

Best ResponseYou've already chosen the best response.0btw forget what I said about partial integration... looks like geting no where.

Best ResponseYou've already chosen the best response.0after IBP, i get the integral of: \[\large [e^{x}(x+1)]^\infty_0\] i made the leap that e^(x) tends to zero much faster than x+1 tends to infinity as x goes to infinity, but can't give a real justification right now

Best ResponseYou've already chosen the best response.0Looks just about right Mathmuse. Seems like I made a bad choise when I did IBP.
