Should be quite easy, really, given that it's just adding things together, hey ho.
Problem
a position vector of point (1), identified by sherical coordinates, is 5m away from point (2).
I have a unit vector R1,2 identified by spherical coordinates [Aex - Bey +Cez], giving the direction to point 2.
How do I find the position vector of point 2
Do I just add 5.0m to each element? Of course not, but how do I do it, please?
