@asish [y]=sin2x shud exist fr x=0,∩/2,∩only as sin2x mst be an integer only .so sum editing reqd

As there have been no changes to the question, assuming that it is correct,
In the interval (0,∩), the graph comes out to be
In (0,∩) sin2x is integral only at x=∩/2=1 =>y= [1,2)
In (0,∩), cos|x| is a positive fraction only for x E (0,∩/2]
Between y=[0,1) the graph is the same as y=cosx
in [1,2) the graph is as y=1+cosx
for the interval, [2,3) the graph assumes y=2+cosx
and so on, using {y}=y-[y]
These two curves only intersect at one point, (∩/2,1)
So the answer is, (∩/2,1)
