question 1

Multiple Choice

The solution of the system $\frac { d x } { d t } = 4 x - y , \frac { d y } { d t } = x + 2 y$ is

• A) \(x = c _ { 1 } e ^ { - 3 t } + c _ { 2 } ( t + 1 ) e ^ { - 3 t } , y = c _ { 1 } e ^ { - 3 t } + c _ { 2 } t e ^ { - 3 t }\)
• B) \(x = c _ { 1 } e ^ { - 3 t } + c _ { 2 } t e ^ { - 3 t } , y = c _ { 1 } e ^ { - 3 t } + c _ { 2 } ( t + 1 ) e ^ { - 3 t }\)
• C) \(x = c _ { 1 } e ^ { 3 t } + c _ { 2 } t e ^ { 3 t } , y = c _ { 1 } e ^ { 3 t } + c _ { 2 } ( t + 1 ) e ^ { 3 t }\)
• D) \(x = c _ { 1 } e ^ { 3 t } + c _ { 2 } ( t + 1 ) e ^ { 3 t } , y = c _ { 1 } e ^ { 3 t } + c _ { 2 } t e ^ { 3 t }\)
• E) \(x = c _ { 1 } e ^ { 3 t } + c _ { 2 } ( t + 1 ) e ^ { 3 t } , y = - c _ { 1 } e ^ { 3 t } - c _ { 2 } t e ^ { 3 t }\)
