It's going to be negative as well. And so these absolute value signs aren't necessary. In the first quadrant, sine of theta and theta are both positive. In the fourth quadrant, they're both negative, but when you divide them, you're going to get a positive value. So I can erase those. If we're in the first or fourth quadrant, our x value is not negative, and so cosine of theta, which is the x coordinate on our unit circle, is not going to be negative. And so we don't need the absolute value signs over there.
