So once again, I'm just subtracting a multiple of two pi, which isn't gonna change the value of cosine. And so this is going to be equal to cosine of three pi over two. And if we imagine the unit circle, let me draw the unit circle here. So it's my y-axis, my x-axis, and then I have the unit circle. So, whoops, all right, the unit circle, just like that. So if we start at, this is zero, then you go to pi over two, then you go to pi, then you go to three pi over two. So that's this point on the unit circle.
