Question

8. (a) Solve the initial-value problem dt and show that sint, n even L 0, n odd in the interval n <K(n +1)T. (b) Solve the initial-value problem dt and show that y()=(n+1) sint in the interval 2nπ〈t〈2(n+1)T. This example indicates why soldiers are instructed to break cadence when marching across a bridge. To wit, if the soldiers are in step with the natural frequency of the steel in the bridge, then a resonance situation of the type (b) may be set up.

I am currently learning about solving differential equations using Laplace transform

and this question is from the chapter about Dirac-delta function.

Thank you!
