Homework Statement
y'=y+y^3
Homework Equations
The Attempt at a Solution
I set y=v, dy/dx = dv/dx. Substituted back into original equation ST dv/dx = v + v^3. Cross multiply, then divide yielded dv/(v+v^3) = dx. After that, I have no clue. The book gives the following answer: y^2 = 1/(C(e^-2x)-1)
Any guidance would be appreciated.
