Not sure exactly where to post this, but I don't see where this is coming from:(adsbygoogle = window.adsbygoogle || []).push({});

[tex] x = Asin \omega t + Bcos \omega t [/tex]

to

[tex] x = Rsin(\omega t + \phi) [/tex]

where

[tex] R = \sqrt {A^2 + B^2} [/tex] and [tex] cos \phi = A/R [/tex] and [tex] sin \phi = B/R [/tex]

I'd be grateful if someone could point out what is going is on here.
