Find the points (if they exist) at which the following plane and curve intersect. y - x = 0; r(t) = (13 cost, 13 sin t,t) , for Osts 4x Choose the correct answer below. O A. The plane intersects the curve at 1312 1312 and 1312 1312 51 2 2 2 2 4 O B. The plane intersects the curve at 1312 1312 It 1312 1312 51 1312 1312 9x 1312 1312 13x 2 2 2 2 4 2 - 2 4 1 , and 2 2 4 O C. The plane intersects the curve at - 1312 1312 3x 1312 1312 71 1312 1312 11x , and 131/2 1312 15x 2 2 4 2 2 4 2 2 2 4 2 2 ' 4 O D. The plane and curve do not intersect on Osts 4n
