the answer will be 2 simply by the graph.
if the ques would be sin (mod x)= mod x then the ans would be 1...

Isn't 2pi a solution? Even pi is..
In addition to what gallardo said,
for x < 0 , x - |x| adds(negatively) up so there wouldn't be any solution.

Very nice ayush but you won't get graphing calculators in exams.

the ques is (sin mod x)= x mod x.....
not sin(mod x)=0....

Ayush....it's x MINUS modx.
For x = npi,
sin(|npi|) = 0
npi - |npi| = 0
This is what the graphing calculator won't tell you.

sorry. i read it as x.modx .. sorry....
then it would have infinite solutions.....
