I missed the class when this was done so I haven't got the notes. Im not sure if this is right but I found these equations

v = w Acos wt

a = -w2 Asin wt = -w2y

Anyone point me in the right direction please?

If you know v=ωA*cosωt

v

Well let's start simple. For the graph of y=sinx, what is the maximum value of y? (the graph oscillated between?)

what is the relationship between ω and the frequency?

Is the max value of y 1? Going back to trig and waveforms.

Isn't ω 2∏ times the frequency?

Isn't ω 2∏ times the frequency?
