1. The problem statement, all variables and given/known data Problem given basically in the beginning of the book, Sec. 1.4, about separable equations. Find general solutions (implicit if necessary, explicit if convenient) of the diff. eq. [tex]dy/dx+2xy^2=0[/tex] 2. Relevant equations There was a previous section where they popped this out of thin air: A solution of [tex]dy/dx=y^2[/tex] is [tex]y=1/c-x[/tex] I'm presuming that that is supposed to be helpful somehow. 3. The attempt at a solution [tex]dy/dx=-2xy^2 => dy/y^2=-2xdx[/tex] Now I can't integrate the left side. I'm sure that is an abysmal way of going at it. So any help would be appreciated.
