    I believe it is best for u to sketch a graph and use the symmetry to work out all the values in that range.

    Draw the angle relative to the x axis. See how many solutions there are in the given range. I'm sorry if this is vague but I can't really explain this over text.

    Try drawing a graph too.

    It can but most people find using graphs much easier.
