p, q, and r are constants. Yes, I know that the derivative of e^t is e^t and all of the derivative rules, but after performing the quotient rule one time I got a huge mess that I could not seem to condense down. That is what I need help with. Ultimately, I am trying to come up with M'(t) =...

Derivative... PLEASE help! Please compute M'(t) and M''(t)? M(t) = (pe^t)^r ------------ (1-qe^t)^r Can use R(t) = ln M(t) if you choose to. Any help is greatly appreciated!

Homework Statement u'''-8u''+2u'-3u=0 Homework Equations The Attempt at a Solution So I let: x1 = u then x1' = u' x2 = u' then x1' = x2 and x2' = u'' x3 = u'' then x2' = x3 and x3' = u''' I have only done these problems with second order equations, so I don't understand...
