4. (45 points) a) Compute the arelength function of the curve b) Find the curvature of the curve (r' , In(t) , the(t)). at the point (1, 0, 0). (Hint: Do not try to compute the curvature for all () c) Find the tangent, normal, and binormal vectors of the curve (cos(f) , sin(t), In(cos ())). at the point (1, 0, 0). (Hint: Do not try to compute the binormal for all t)
