4) f(x) = sinh(x) tanh (x)

5) f(t) = tanh(e^t)

Any help will be appreciated. Also, I know this is sort of the quick fix forum, but if you could possibly include how to solve each problem, it would be much appreciated. After all, I need to be able to figure this out come test time.

**Nevermind guys, I got it.**
