I know the answers, as Wolphram Alpha has given me only the answers without any steps to how they derived those answers. I know that sin(x)=√3/2 x= Π/3 & 2Π/3, and I know that the 2 to the left of the x means that I have to divide my answers by 2, but what about that -Π/6? What do I do with it? I have no clue where to go from here. I saw tons of youtube videos and websites describing how to solve trig equations, but they never talk about ones that have the 2 and -Π/6 inside the brackets! What do I do?
