FLASH: Algebra Question

[Wil Roboly/Big Orbit]

For anyone out there who can figure this out, you'll get a big sweet

lollipop.


If I have two points P(x1,y1) Q(x2,y2) in 2-space, where P is my origin, how

do I find the angle theta created by the vector |PQ|? What would be easier,

to get theta in degrees or find the Arc in Rads?
