WebApr 16, 2024 · X there is positive and Y is negative. I understand that the radius in a unit circle is 1. This makes the sin of a 330 degree angle -1/2. But from the definition of sin = opposite/hypothenuse, it should always be positive since the length of a triangle should always be positive. I haven't seen a length of -2cm. So why is it different here?
