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

I am a bit lost with the equations for velocity:

I don't know Calculus yet, so my teacher just gave me the equation:

-wx_{0}cos(wt) (w being omega)

He then said: v_{0}= wx_{0}

and therefore, concluded: -v_{0}cos(wt)

and then for when the displacement is maximum at time = 0: v_{0}cos(wt)

Is this correct? I mean, I am obviously not doubting him but I am a bit confused plus my notes were not very organized on this day...

Thanks in advance
