Find the number of intersections between the image of the function y = SiNx, X belonging to (0,2 π) and the image of half of the function y One in two of Y is y = one in two

Find the number of intersections between the image of the function y = SiNx, X belonging to (0,2 π) and the image of half of the function y One in two of Y is y = one in two

First draw the image of y = SiNx
And then draw the image where y equals one-half
If x is in the range of (0,2 π)
It can be concluded that there are two intersections with y = 1 / 2
