Points: U of 1 Determine whether the given vector functions are linearly dependent or linearly independent on the interval ( - co, co). sin (10t) sin (20t) cos (10t) cos (201) sin (10t) sin (20t) Let x1 = and x2 = Select the correct choice below, and fill in the answer box to complete your choice. sin (10t) . cos (20t) - cos (10t) . cos (10t) cos (20t) O A. 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, deffx, (t) x2(t)]= O B. The vector functions are linearly independent since there exists at least one point t in I where det fx, (t) x2(t)] is 0. In fact, detfx, (1) x2(t)]= O C. The vector functions are linearly dependent since there exists at least one point t in I where det fx, (1) x2(t)] is not 0. In fact, detfx, (t) x2(t)] = D. The vector functions are linearly independent since there exists at least one point t in I where det fx, (t) x2(t)] is not 0. In fact, detfx, (t) x2(1)] =
