A curve is defined by such that
Show that T and T' are always orthogonal by using |T|=1
edit: this should only take a few lines of working
i've tried using dot product =0 because the angle is 90 but i've no idea where to take that from there
I accept with information:A curve is defined by r(t) such that r'(t) \neq 0
T(t)=\frac{r'(t)}{|r'(t)|}
Show that T and T' are always orthogonal by using |T|=1
