Advanced Question Translating Degree Units to Vectors?

[ChristopherT]

What I looking for is a way to translate the 360' in a circle to the vectors for the Docking Port DIR command. I'm working on a station that has 3 docking ports on top, equally spaced, for 120 degrees of seperation. I also have 15 docks in the middle section to deal with. I'm using Vinka's SP3. I believe the current system supports 6 possible directions?

Thanks!

sin() and cos() along with their inverses is pretty much all the special math you need.

Any possibilities of less Trig??

For Vectors it's simply the unit circle. Cosine is your x-value, Sine is your Y value. Just be careful about positives and negatives. 2pi/3 is 120 degrees so using the pic below, (x,y) (cos,sin)

That actually makes sense! The chart makes it a lot clearer and I think I can handle that math!
