## M 5 years ago Mx(t) = p^et/[1-q^et] dMx(t)/dt =?

1. anonymous

what does p and q stand for ? could you use the equation button to express it ?

2. anonymous

quotient rule $\frac{dM}{dt}= \frac{(e ^{t}\ln p (p ^{e ^{t}})(1-q ^{e ^{t}}) + (e ^{t}\ln q (q ^{e ^{t}})(p ^{e ^{t}})}{(1-q ^{e ^{t}})^{2}}$

i'm guessing there is no short cut to solve this?

4. anonymous

ln is not neccessary to derive this right

5. anonymous

not really, the quotient rule is the shortcut i guess (f/g)' = f'g - fg'/g^2

6. anonymous

i think it is, dervitive of a^x = ln(a)*a^x

ok thanks

can i talk to anyone on fb?
