whether γ=γ(s):I->R^3 curve parameterized as to arc length (single speed). Assume that γ is the surface sphere centered on the origin (0,0). Prove that the vector t(s) is perpendicular to the radius of the sphere at point γ(s), for each s.
i know that t(s)=γ΄(s) but i don't know how to continue to prove it , maybe i don't have undrstand the problem on how to show that t(s) is vertical on the radius of sphere
