There can be one Graphical approach to this question, see below :-

Explanation:

Since,

#2sinx-1=0#

#rArr sinx=1/2#

Now plot the graphs of #y_1=sinx# and #y_2=1/2# on same graph paper ; the point of intersections of both the graphs (#ie.# #y_1=y_2#) will be the solutions to the equation #2sinx-1=0#.

See the pic given below , the intersection points shown below are some of the infinite possible solutions to the given equation #2sinx-1=0# .
