Question

Mx(t) = p^et/[1-q^et]

dMx(t)/dt =?

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

ln is not neccessary to derive this right

Answer 5

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

Answer 6

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

Answer 7

ok thanks

Answer 8

can i talk to anyone on fb?
