Question

du/dr=(1+sqrt(r))/(1+sqrt(u))_

Answer 1

...

Answer 2

\[\frac{du}{dr}=\frac{1+\sqrt{r}}{1+\sqrt{u}}?\]

Answer 3

yes

Answer 4

that is a statment

Answer 5

what would you like to do with that information?

Answer 6

solve differential equation

Answer 7

ahhhh

Answer 8

its seperable..

Answer 9

yes it is

Answer 10

this is how far i got but i want to know if its right.
[u+u ^{3/2}=r+r ^{3/2}+C\]

Answer 11

That is supposed to be:\[u+\frac{2}{3}u^{3/2}=r+\frac{2}{3}r^{3/2}+c\]

Answer 12

oh snap your right

Answer 13

i forgot that step.-_- thanks:D

Answer 14

but don't i have to get "u" by itself?

Answer 15

Usually, you should, but it is unfeasible to do that for this particular ODE (is inhumanely long).

Answer 16

okay thankyou
