    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.

    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

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

    I am sure they will keep the advice regarding growing stars in mind if/when it's needed; no need to repeat :)

    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.
