Question
Determine whether the functions y,
and y, are linearly dependent on the interval (0,1).
y1 =sint cos t, y, = 5 sin 2t
Select the correct choice below and, if necessary, fill in the answer box within your choice.
O A. Since y, = y, on (0,1), the functions are linearly dependent on (0,1).
(Simplify your answer.)
O B. Since y, =O2 on (0,1), the functions are linearly independent on (0,1)
(Simplify your answer.)
O C. Since y, is not a constant multiple of y, on (0,1), the functions are linearly independent on (0,1).
O D. Since y, is not a constant multiple of y, on (0,1), the functions are linearly dependent on (0,1).
