## kantalope Group Title amiright? integrate: ((e^(2x)) / e^x cant i treat that at ((e^(2x)) * e^(-x) which would just simplify to e^x??? 2 years ago 2 years ago

1. kantalope Group Title

and even I can integrate e^x

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 :(

4. TuringTest Group Title

yes and yes

5. kantalope Group Title

yay me...that question has stumped me for a week

6. TuringTest Group Title

$\int e^xdx=e^x+C$$\frac d{dx}e^x=e^x$so those are pretty easy to remember ;)

7. kantalope Group Title

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

8. TuringTest Group Title

if it's$\int_{a}^{\infty}e^xdx$or any integral over +/-infinity of e^x like that, yeah, it diverges

9. TuringTest Group Title

sorry, NOT if it's negative infinity

10. TuringTest Group Title

$\int_{-\infty}^{a}e^xdx$converges

11. kantalope Group Title

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

12. TuringTest Group Title

good luck!

good luck with your Exam :)
