I sense a homework dump coming on.
I'll do this one, then you can show some work on the rest.
sin(x + π) − sin x + sqrt(3)=0
-sinx - sinx = -√3
sinx = √3/2
sinx is positive in QI,QII, so the solutions are
π/3, 2π/3
Find all solutions of the equation in the interval [0, 2π). (Enter your answers as a comma-separated list.)
