Determine whether the given vector functions are linearly dependent or linearly independent on the interval ( - co, co). sin (7t) sin (14t) cos (7t) cos (14t) Let x1 = sin (7t) sin (14t) and x2 = Select the correct choice below, and fill in the answer box to complete your choice. sin (7t) . cos (14t) - cos (7t) . sin (14t) cos (71) cos (14t) O A. The vector functions are linearly independent since there exists at least one point t in I where det x, (t) x2(1)] is 0. In fact, det x, (t) x2(t)] = O B. The vector functions are linearly independent since there exists at least one point t in I where det x, (t) x2(t)] is not 0. In fact, det x, (1) x2(1)]= O C. The vector functions are linearly dependent since there exists at least one point t in I where det x, (t) x2(t)] is 0. In fact, det x, (t) x2(1)]= D. The vector functions are linearly dependent since there exists at least one point t in I where det x, (t) x2(t)] is not 0. In fact, det x, (t) x2(1)] = Textbook Ask my instructor Print Clear all Check answe
