Extracted text: Which curve has the greater length on the interval [- 1,1], y = 1-x or y = cos (Tx/2)? Use left Riemann sums with n = 10° to approximate the lenghts of each curve. Select the correct choice below and fill in the answer boxes to complete your choice. (Round to three decimal places as needed.) O A. The curve of y = 1-x has a length of unit(s). The curve of y = cos (TX / 2) has a length of unit(s). Therefore, y = 1-x has the greater length on the interval [- 1,1]. Ов. O B. has a length of 2 The curve of y=1-x unit(s). The curve of y = cos (tX / 2) has a length of unit(s). Therefore, y = cos (TX/2) ha s the greater length on the interval [- 1,1].
