Question:

If $y=A \sin x+B \cos x$, then which of the following is correct?

Options:

$\frac{d^2 y}{d x^2}-y=0$

$\frac{d^2 y}{d x^2}+y=0$

$\frac{d^2 y}{d x^2}=\frac{d y}{d x}$

$\frac{d^2 y}{d x^2}=\frac{-d y}{d x}$

Correct Answer:

$\frac{d^2 y}{d x^2}+y=0$

Explanation:

The correct answer is Option (2) → $\frac{d^2 y}{d x^2}+y=0$
