Nasty integral -- which piece of technology to trust?
indefinite integral: e^x / (e^2x + 9) dx
Technology is allowed to solve it.
My trusty TI-89 says (pi/540)arctan((e^3x)/3)
while two different online integral calculators came up with (1/3log(e))*arctan((e^3x)/3)
What do you think? Which is right/should I trust? Should I just do it by hand? If so, what method do you recommend?
Thanks
