# Plotting Phase Space [duplicate]

I have these two Equations

\begin{align} x'(t)&=\sin(y)\\ y'(t)&=\cos(x) \end{align}

and I'm trying to plot the phase space(plane) for this system... I've tryed Equationtrekker but can't seem to find the way to use it this way.

Maybe this? StreamPlot[{Sin[y], Cos[x]}, {x, -2, 2}, {y, -2, 2}] – user10957 May 25 '14 at 15:37
