amiright? integrate: ((e^(2x)) / e^x cant i treat that at ((e^(2x)) * e^(-x) which would just simplify to e^x???
and even I can integrate e^x
hehe o please help...i'm dying here
yes , you are completely right because we subtract powers in division , and don't forget to write C (constant of integration) I often forget it :(
yay me...that question has stumped me for a week
\[\int e^xdx=e^x+C\]\[\frac d{dx}e^x=e^x\]so those are pretty easy to remember ;)
luckily no need for c the real question is does that converge or diverge and since e^x heads for infinity I can say diverge with more than my usual 50/50 chance of getting it right thanks all
if it's\[\int_{a}^{\infty}e^xdx\]or any integral over +/-infinity of e^x like that, yeah, it diverges
sorry, NOT if it's negative infinity
\[\int_{-\infty}^{a}e^xdx\]converges
ah good point - i will keep an eye out for that on the test tomorrow...all of our practice questions have been positive though so that would be cruel
good luck with your Exam :)
