WebApr 16, 2024 · 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? Why can't we just say that the sin of a +330 degree angle is 1/2. Why should we make it negative. WebAug 8, 2011 · Copy. The inverse (negatives) of sine, cosine, and tangent are used to calculate the angle theta (or whatever you choose to name it). Initially it is taught that opposite over hypotenuse is equal to the sine of theta. sin (theta) = opposite/hypotenuse. So it can be said that. theta = sin-1 (opp/hyp) This works the same way with cosine and …
