How do you prove that (sinx-cosx-1)/(sinx+cosx-1)=(cosx+1)/sinx?

Perhaps there was a mistype in this question:
Here is the graph of
graph{(sinx-cosx-1)/(sinx+cosx-1) [-10, 10, -5, 5]}
Here is the graph of
graph{(cosx+1)/sinx [-10, 10, -5, 5]}:
It's flipped around, meaning the identity is false: one side of the equation is the negative of the other. If there was a negative sign on one side of them, then we could probably prove it.
