    @dragonkeeper999, thanks once again

    Now I have to find all the points of intersection of the x-coordinate in the interval 0<x<360. I couldn't factorise it so I put it through the quadratic equation, got -2 and 1, -2 not a solution so went with 1, inverse of san gave 90 and 110, which isn't the right answer
