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

1. Yuki

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

2. dumbcow

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

3. M

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

4. M

ln is not neccessary to derive this right

5. dumbcow

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

6. dumbcow

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

7. M

ok thanks
