Find the arc length parameter along the curve from the point where t= 0 by evaluating the integral s = | |v(t)| dt. Then find the length of the indicated portion of the curve. r(t) = (6 + 4t)i + (9 + 3t)j + (1 - 3t)k, - 1sts0 The arc length parameter is s(t) =. (Type an exact answer, using radicals as needed.) The length of the indicated portion of the curve is (Type an exact answer, using radicals as needed.)Find T, N, and * for the space curve, where t> 0. r(t) = (2 cos t + 2t sin t)i + (2 sin t - 2t cos t)j + 2k T = ()i+ (Di (Type exact answers, using radicals as needed.)
