The problem involves finding the exact value of the sine function for the angle 240º, which is situated in the context of trigonometric functions and their properties in different quadrants.
The discussion is ongoing, with participants exploring different approaches to understand the relationship between the angle and known sine values. Some guidance has been offered regarding angle relationships, but there is no consensus yet.
There is a mention of the sine function's sign in different quadrants, particularly noting that sine is negative in the third and fourth quadrants, which may influence the understanding of the problem.
sin is -ve in 3rd and 4th quadrantCorkery said:so 240 is 60 degrees more than the 180 line of quadrant 2 so sin 60 = √3/2. is that right or am i totally off?
