# Non homogeneous second order ODE watch

1. Where is a positive constant and the constant lies in the interval

I'm familiar with solving second order ODEs however the constant k lying in that interval is throwing me off. Could someone walk me though it?

It would probably be more helpful if you posted your attempt at it and hopefully I, or someone else, will be able to get you back on the right track.

The interval of k only means that the caharacteristic polynomial of homogeneous part will have complex roots. Solve according to this.
