    Hi
    The question is solve each equation for x in the interval 0<x<2pi

    Cot^2x-3cosecx+3=0

    so far I have values for cosec as: -1 and 4

    However looking at the answers it says to convert to sin you end up with sins = 1/2 or 1 but I don’t understand how they got that?

    Any help would be really appreciated!! Thanks!

    You didn't get the correct cosec values. In addition, 1/sin = cosec - your title says cosine for some reason
