What's the derivation for u hat here? I'm lost on how we got there.

BlueCat

I have the same question, how did we get u hat?

richardnnn

I think u hat is obtained similarly like how we obtain matrix to represent the dot product, where we first compute the result of cross product, and compare it with v to figure what each entry is on the matrix?

snaminen

How did we get -uv = u^Tv? Does this generally hold or is it a special property of u hat?

minhsual

How do we generalize the procedure from u to u_hat with vectors that represent other dimensions?

Is it possible to elaborate the last proven more?

Can we approximate all transformations with matrix representation in graphics?
