The helix of radius R, height h, and N complete turns has the parametrization r(t) = ( Rcos 2nNt 2n Nt h ), Rsin h ), t), ostsh Calculate the length s of a helix if R = 4, h = 7, and N = 10. (Use symbolic notation and fractions where needed.) S =Find an arc length parametrization r1(s) of the curve r(t) = (e' sin(t), e' cos(t), 6e'). (Give your answer using component form or standard basis vectors. Express numbers in exact form. Use symbolic notation and fractions where needed.) W) = E
