I'll do that over here. So if you have a common denominator, that is six pi over four, the same thing as three pi over two, minus pi over four, sorry, minus pi over four is equal to five, five pi over four. So it's sine of five pi over four, five pi over four, over cosine squared of five pi over four, and then times negative one. 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.
