Answer:
i think A is answer you should to do
X = 2i, -2i (I’m sorry if it does come back as wrong but it’s the only answer I got)
For trigonometry, the main components that comprise this topic are the special wave functions, sine, cosine, and tangents. You need to understand their relationships with each other, and further develop your understanding on their role in geometry.
You need to conceptually grasp how right angle triangles are formed, and how to develop angles and sides based on incomplete information, using the three main wave functions.
On top of this, you will need to understand how each wave function transforms, such as being able to graph such wave functions with a change in amplitude and period. When doing trigonometry, you will also need to understand the subtle differences between radian angles and degree angles, and how to convert radians into degrees and vice versa.
