Derivation of simple harmonic motion
I'm looking at the wikipedia page for simple harmonic motion (http://en.wikipedia.org/wiki/Simple_harmonic_motion) and I'm confused by this line:
[tex]c_1cos(\omega t) + c_2sin(\omega t)=A*cos(\omega t - \phi)[/tex]
How did they get from the left hand side to the right hand side?
Also what is the significance of omega? Apparently it means angular frequency but why does it equal [tex]\sqrt{\frac{k}{m}}[/tex]
