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

There is no such x, $0 < x < \pi$.

$sin(x) - 1 = 0$

$sin(x) = 1$

For what values of x is sin(x) = 1?

$x = 0, \pi$

Neither of which is in your indicated domain.
