Note that this function is even. (Because sin(pi-x)=sin(x))

OHHHHHH So what Why mod I don't get it wait lemme check notes Wait won't it be an odd function? Cuz f(-x) = -f(x) Oh wait no It's not odd but still mod x makes no sense

Actually in the intermediate solving you would get something like arccot(cot(some stuff)), the some stuff is in the range of (-pi/2,pi/2), when the "some stuff" is -ve the value obtained is pi-mod(some stuff) while when it is positive, the value obtained in argument of sine is (some stuff). Sorry for the crass explanation, but I will try to send a more elaborative explanation later.
