dx/dt = -x

^{3}+ 2*x + sin

^{3}(2*pi*t) - 2*sin(2*pi*t) + 2*pi*sin(2*pi*t)

has the solution:

ψ(t,0,0) = sin(2*pi*t)

I know that I need to get all of the x's on one side and the t's on the other then integrate, but I can't figure out how to get the x's and t's together. Is there a little trick or something to solving this?

Thanks a lot.
