    It looks separable to me.

    i got it to \[- e ^{\cos(x)} = y^{-1} +C\] is this correct first off?

    Put the arbitrary constant on the other side. It is arbitrary, so it doesn't matter which side of the equation it is on.

    Does that make sense?

    Well, if we have\[y^{-1}=C-e^{\cos(x)}\]We can simply take the reciprocal of both sides, provided that it doesn't equal zero:\[y=\frac{1}{C-e^{\cos(x)}}\]
