Physics Vector Question.

[Cygnus A]

We had magnitudes and angles, so added two using law of cosines or whichever I don't remember, then added the resultant to the third and got it right, but I was wondering if we could add more than two that way at a time.

You can add unlimited vectors at once. In the 2D plane you use sin/cos to break them down into their x/y components. In 3D, you need to move into matrix algebra.

I'm remembering that a bit now. It's been forever.
