    (a) You want to solve 0 = a \sin \theta and 0 = a \theta \cos \theta in conjunction, what obvious value of \theta solves those two equations?

    So theta =0 ?

    Yes. Now think about what values of \theta corresponds to A and B, hint: the y-axis is at \frac{\pi}{2} to the x-axis.

    Sorry, i don`t understand how to do that.

    The Cartesian equation can be found here but it is unnecessary.
    Solve for when x and y =0 and did the corresponding θ values.

    What does an x-axis or y-axis intercept mean for the x,y coordinates?

    Y=0 at an X intercept, and X=0 at a Y intercept.
    so B is (?,0) and A is (0,?).

    Yes.
    I just don`t see how i can plug this in to get x value for B and a y value for A.

    Find a value of \theta that makes x zero then plug this \theta into your y. Then vice-versa.
