Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I have learned that linear SHM is just projection of UCM onto one axis. Is angular SHM also related to UCM ?

Moreover, I have also learned that theta = theta0 * sin(wt+P) where theta is angular displacement, theta0 is angular amplitude and P is phase constant. Where does this equation come from, or how can I derive it ?
