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...
