I could just put that out here. Now what is sine of five pi over four and cosine squared of five pi over four? Well, I don't have that memorized, but let's actually draw a unit circle and we should be able to figure out what that is. So a unit circle, I'm gonna try to hand draw it as best as I can. Please forgive me that this circle does not look really like a circle. All right. Okay, so let me just remember my angles.
