Find the arc length parameter along the curve from the point where t=0 by evaluating the integral s = |vidt. Then find the length of the indicated portion of the curve. 0 r(t) = (e' cost)i + (e sint)j + ek, - In 4 st0 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.) units.
