Our goal is to graph f of x is equal to negative sine of x.
00:05
Now, our vertical shift is zero.
00:11
Our amplitude, this time, is negative 1.
00:15
Our horizontal shift is 0, and our k value is 1.
00:20
So our period is going to be 2 pi over 1, which is 2 pi.
00:25
Now, this is just a shift through the x -axis.
00:30
So the x equals 0, sine of x is going to be equal to 0.
00:38
Not reflect through the x -axis because it's on the x -axis.
00:42
At sine is equal to pi halves, sorry, x is equal to pi - halves...
