RE: FLASH: Algebra Question

[Glen Rhodes]

sin Theta =           (y2 - y1)

            ----------------------------

            sqrt( (y2-y1)^2 + (x2-x1)^2 )


Then.. take the arcsin of that.. that's your angle.


That's just length of the Y side over the length of the distance

(hypotenuse) between the points.

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?
