What's a good strategy for finding the angle for each quadrant? @MarkFL Thanks.

I would write something like: \(\displaystyle v_x=350\cos\left(95^{\circ}\right)\) \(\displaystyle v_y=350\sin\left(95^{\circ}\right)\)

How about for negative angles (any quadrant) or positive ones in the 3rd and 4th quadrants?
