Answer:

We know that
and using this identity we have:


And if we remember the equation above represent the fundamental identity in trigonometry and is satisfied for every real number and we can say that the solution for this case is:
![A= [X | x \in R]](https://tex.z-dn.net/?f=%20A%3D%20%5BX%20%7C%20x%20%5Cin%20R%5D)
Step-by-step explanation:
For this case we have the following equation given:
