I understand that in case of symmetric inequalities, you can assume $$a \geq b \geq c$$ without loss of generality because you can replace for example $$a$$ with $$b$$ but still the inequality remains unchanged.

Trig question finding all solutions
what is the best way to find all the solutions of sin x-1=0, with the answer in A+Bkpi, where A=? with 0<A<pi
where B=? and k is any integer
Thankx
