Question

find a solution for \[(y - \cos^2 x)dx + \cos x dy = 0\]

Answer 1

do i divide by cosxdx?

Answer 2

i'm trying to figure out which method would work best lol

Answer 3

you might be able to ge this into a linear

Answer 4

oh wait maybe y=ux

Answer 5

y=ux

dy=udx+xdu

Answer 6

\[\frac{dy}{dx}+\frac{y}{cosx}=cosx\]

Answer 7

homogeneous??? o.O

Answer 8

i hate that thing lol

@THE_PROPHET so you divided by cosxdx right?

Answer 9

yup

Answer 10

ok thanks
