Determine whether the following curve uses arc length as a parameter. If not, find a description that uses arc length as a parameter. = 1+√7320 r(t) = cost, 1 √2 cos t, sin for Osts4 Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. OA. r(t) does not use arc length as a parameter. A description of the curve that uses arc length as a parameter is r(s) = for Sss (Type exact answers, using radicals as needed.) B. r(t) uses arc length as a parameter.
