Determine whether the functions y, and y2 are linearly dependent on the interval (0,1). Y1 = 2 cos?t-1, y2 = 4 cos 2t Select the correct choice below and, if necessary, fill in the answer box within your choice. A. Since y, = (y2 on (0,1), the functions are linearly dependent on (0,1). (Simplify your answer.) O B. Since y, = (y2 on (0,1), the functions are linearly independent on (0,1). (Simplify your answer.) OC. Since y, is not a constant multiple of y2 on (0,1), the functions are linearly dependent on (0,1). O D. Since y, is not a constant multiple of y2 on (0,1), the functions are linearly independent on (0,1).
