My prof has written out a derivation which says:

[tex]\vec{a_{t}}[/tex] = α x [tex]\vec{r}[/tex]

Why does everything except α have a vector sign on it? I think α should be a vector here too...

By the way, he also derived dv/dt = ω, and v had a vector symbol but ω did not. Is that right or should ω be a vector?
