    This is part 7b of FP2 June 2014 International Paper

    The question asks for "Five distinct solutions of the equation"

    My question is, what does distinct mean? Does that mean positive? The mark scheme only shows positive roots when the first is -pi/6 in my work.

    If you want a link, here it is and its question 7B:

    Oh, you mean roots for \theta? It doesn't matter whether you use negative or positive - recall that \sin(x+2\pi) = \sin(x), so we can transform any negative-\theta situation into a positive-\theta one.
