3sinx+1=sinx 2sinx+1=0 2sinx=-1 sinx=-1/2 x=sin^-1 (1/2) = 30 = [tex] \pi [/tex]/6 (when finding the inverse, always take the positive value, ignore the negative sign) x is therefore negative in 3rd and 4th quadrant Therefore values of x are: 180+30=210 = 7[tex] \pi [/tex]/6 360-3=330 = 11[tex] \pi [/tex]/6
