What do you mean by "solve"? It looks as though you are trying to represent a set of polar coordinates. I could guess that you want to convert polar to rectangular coordinates. But we don't like to guess; this is mathematics after all. So when you figure out what you want and how to ask for it correctly, repost your question.
