hello...(adsbygoogle = window.adsbygoogle || []).push({});

I was wondering if someone can help me fully understand the equations of SHM:

x(t) = A cos (wt + theata)

v(t) = -A sin (wt + theata)

a(t) = -A cos (wt + theata)

you see... i know that A is the amplitude and that theata is the phase shift. I know that w is agular frequency, but i dont know what it does and how to find period with it.

My real problem is the t infron of w. I have no idea what that is and I have know idea how to use it in a calcuation.

Can someone please explain to me a good general vieow of how to interpret these euqations.

Thanks
