QuestionEach of the following are equal to Sin⁡(A)\operatorname{Sin}(A) EXCEPT
A sin⁡(−A)\sin (-A) B sin⁡(π−A)\sin (\pi-A) (C) cos⁡(90∘−A)\cos \left(90^{\circ}-A\right)
D 1csc⁡A\frac{1}{\csc A}

Studdy Solution
Options B, C, and D are all equal to sin⁡(A)\sin(A).
Only option A, which simplifies to −sin⁡(A)-\sin(A), is *not* equal to sin⁡(A)\sin(A).
Thus, the answer is A.
