Answer:
Step-by-step explanation:
(1)
a1=-2
r=-2

we can factor the whole thing:
(2sin(x) -1)(sin(x)+1) = 0.
Therefore, sin(x) = -1 and sin(x) = 1/2.
For the first one x = 3π/2 and the second is π/6 and 5π/6
So 3π/2, π/6 and 5π/6 are the solutions.
I do kind of have a problem with this because it doesn't mention if you should go over 360°. Otherwise, you have to add in an 2nπ into the equations like 3π/2 + 2nπ; 
but I don't know if that is necessary for you.
Answer:

Answer: I believe this will be your answer for this.
<u>x = </u>
<u> so basically this is your solution of x equaling to 2 over 729.</u>
