(Solved): Let \( y(t) \) be the solution of \( y^{\prime \prime}+y=\delta(t-2 \pi)+\delta(t-4 \pi)=0, y(0)=1, ...
Let \( y(t) \) be the solution of \( y^{\prime \prime}+y=\delta(t-2 \pi)+\delta(t-4 \pi)=0, y(0)=1, y^{\prime}(0)=0 \). Then \( y\left(\frac{9 \pi}{4}\right)=\ldots \ldots \). \( \sqrt{3} \) \( \sqrt{2} \) 1 \( -1 \)
