\[\frac{dy}{dx}=y-y^2\]
OpenStudy (usukidoll):
\[dy \frac{1}{y-y^2}=dx\]

I know the right hand side is x + C by default. but wtheck is going with the left...
OpenStudy (usukidoll):
I don't think I can split the fraction... so I tried u subsitution which is u = y-y^2 du = 1-2y
OpenStudy (usukidoll):
but then I get something screwed up and aarrrrghhhh wtheck.

\[\int\limits_{}^{}\frac{1}{y(1-y)} dy=\int\limits_{}^{}1 dx\]
use partial fractions for left hand side
myininaya (myininaya):
right hand side is pretty easy
OpenStudy (usukidoll):
oh of course x.x that's the A/wfsdjfsdkl B/ sfjdslkfjdskl such and such
myininaya (myininaya):
\[\frac{1}{y(1-y)}=\frac{A}{y}+\frac{B}{1-y} \text{ yeah }\]
OpenStudy (usukidoll):
A/y + B/1-y stuff right? since it's factorable in the denominator... yeah now I remember you're a godsend thank you :)
