Okay, so this question is asking us to explain the period and frequency of a simple harmonic motion graph and how are they related to each other.
00:12
So for simple harmonic motion we're gonna have something like d equals some amplitude times either sign or cosine.
00:25
They end up being fairly similar just changes where you start whether you start at zero or start at one of omega t w looking guy is a lowercase omega.
00:38
So period is given by 2 pi divided by omega and the frequency is given by omega divided by 2 pi.
01:02
So with that in mind it shouldn't be too surprising that the frequency is just one over the period.
01:14
Also period is just one over the frequency.
01:20
So that's kind of how they're related.
01:22
Let's take a look at what they actually mean.

On a graph of some trig function, let's say i'm using sign, so i'll draw a sign graph...
