Consider the solutions y 1 (t) = [e -3t , e -3t , 0] T and y 2 (t) = [0, e -5t , e -5t ] T to the homogeneous linear system of differential equations y'(t) = Ay(t), where A is the 3 × 3 matrix: A = [-5 2 -2] [ 1 -4 -1] [-1 1 -6] Which of the following statements is true?
- 1y 1 and y 2 are linearly dependent.
- 2There exists another solution y 3 such that {y 1 , y 2 , y 3 } forms a basis for the set of all solutions to the system.
- 3y 1 and y 2 are linearly independent but do not form a basis for the set of all solutions to the system.✓
- 4y 1 and y 2 form a basis for the set of all solutions to the system.
Correct answer
y 1 and y 2 are linearly independent but do not form a basis for the set of all solutions to the system.
