i've been reading on the internet about vectors and i keep seeing this stuff about "i, j, k". I am learning vectors in physics but my teacher hasnt mentioned any of this stuff. I've read that if "i, j, k" are the components of the x, y and z axis? and that when u multiply two different letters u get 0 and to like letters u get 1. basically what I am asking is can u help me understand wat these letter means n wat we use them for?
thanks
thanks
