00:01
So the period will be 2 pi over 240, which is pi over 120.
00:12
So it's like 0 .02618.
00:20
I guess that's good enough.
00:21
And then so here's 1 .5.
00:28
And then it's going to oscillate from 1 .5 to 1 .75 and then 1 .25.
00:36
And it's a sine curve, but it is shifted.
00:40
Okay.
00:42
So, so this is a graph of sine.
00:46
So it's going to go like this and you know, it's going to go like that until, i mean, it's, i'm not drawing well enough because it's, it's, um, and there are like, if you divide this number, which is the period, you know, from peak to peak, like this is the period, right? so 3 divided by that number is like 114 plus, um, there are that many cycles there.
01:25
Okay.
01:26
So in here, um, but the key idea is the period is this.
01:32
And then let me see what else is asking the graph.
01:35
We did it.
01:36
Uh, this is t.
01:37
This is y.
01:39
And then you should know that in the graph, the highest and lowest point is from 125, 1 .25...
