Question 547735: Find all real solutions to the equation: 4 sin (2x-pi/3)=0
Answer by mathie123(224)   (Show Source): You can put this solution on YOUR website!

Dividing both sides by 4


Now looking at the y=sin(x) graph we have


We can see that the graph has a y value of 0 ever 180 degrees (though it is a bit hard to see as this graph is in radians, this is a known fact) (or 180*k where k is an integer).

So we get (from now on k is an integer)





Hopefully this helps! Let me know if you are unsure still.
