Q. 45

Mark the correct alternative in each of the following:

Which of the following differential equations has y = C1 ex + C2 e–x as the general solution?





Answer :

Solving for (A)

For general solution put (D2 + 1) = 0

General solution, y = C1 cos x + C2 sin x

Solving for (B)

For general solution put (D2 – 12) = 0

General solution, y = C1 ex + C2 e-x = (B) which is required solution.
