LOST DOVE ARE YOU THERE

yes. but I thought someone here might answer my question :S

Whenever you take the derivative of e^x, it's e^x. If you take the derivative e^kx where k is a constant, the derivative is ke^kx.

LOST DOVE USE ONLINE TUTORING BUT PLZ DONT USE TUTOR NEXT OR TUTROR VISTA U CAN USE GROWING STARS

Make sure you think of e^-x as e^-1x. Each time you take the derivative, the sign will change. That's why -e^-x will derive to e^-x

GREAT IDEA

BUT USE ONLINE TUTORING

When thinking of the antiderivative/integral of e^kx, the answer will be 1/k*e^kx

google "paul's online math notes". It's a website created by a professor, it's gotten me through calculus. It's free, not a tutoring site like Sassy is saying (lots of money, unexpected results). He has his lecture notes online and explains everything taught from algebra all the way through differential equations.

yeah. I was having trouble keeping up with both convos.
