I'm surprised. Not at the fact that you couldn't do it, but the fact that you have no idea.

Actually, I figured it out.

If I may paraphrase a prayer I once learnt: "... Take time to think ..."

You don't know how true that is.

nah nah... it's just a wanky sentence you need to remember is that "the perpendicular vector is the cross product of the two vectors" , so basically you just do the cross product of thw two vectors, so then you get a vector, and you find the unit vector from it :)

to find a vector perpendicular to 2 other vectors you take the cross prouct of those other 2
