Two Linearly Independent Solutions of the Differential Equation $y ^ { \prime \prime } - 4 y ^ { \prime } + 5 y = 0$

question 35

Multiple Choice

Two linearly independent solutions of the differential equation $y ^ { \prime \prime } - 4 y ^ { \prime } + 5 y = 0$ are

• A) \(y _ { 1 } = e ^ { x } , y _ { 2 } = e ^ { 5 x }\)
• B) \(y _ { 1 } = e ^ { - x } , y _ { 2 } = e ^ { - 5 x }\)
• C) \(y _ { 1 } = e ^ { 2 x } \cos x , y _ { 2 } = e ^ { 2 x } \sin x\)
• D) \(y _ { 1 } = e ^ { x } \cos ( 2 x ) , y _ { 2 } = e ^ { x } \sin ( 2 x )\)
• E) \(y _ { 1 } = e ^ { - x } \cos ( 2 x ) , y _ { 2 } = e ^ { - 2 x } \sin ( 2 x )\)
