    For trig equations when we're given bounds of -180>180 or something like that, how do I get the negative solutions? I know how to get the postive ones

    Draw the graph between -180 and 180. Then draw a horizontal line through your solution stretching across the entire graph. The places where this line intersects the graph again is where the other solutions are so use the symmetry of the graph to help you
