How do I solve this differential equation:
, c and m are constants larger than 0. Initial conditions are x(0)=a, x'(0)=0.
I don't understand something, if you have a harmonic oscilator differential equation:
the solution is:
So why don't you get solution x(t)? Or do you suggest that solution is:
If so, I don't think that's a solution, try puting it in initial equation.
