    4*csc^2(a)= 1

    csc^2(a) = 1/4

    csc(a) = +/- 1/2

    then ask yourself, for what values of "a" is csc(a) = +/- 1/2
    (or think in terms of sine, if that helps)

    I think there's something wrong with the question.

    csc is 1/sin so you're saying sin(x) = 2. That's impossible... sin oscillates between -1 and 1.
