Yeah, so this is, so we could view this as, we could subtract, let's subtract four pi, which is going to be, we could write that as eight pi over two. In fact, no, let's subtract five. Let's subtract, no, let's subtract four pi, which is eight pi over two. 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.
