eljaja · Answer

I can't take screenshots on this computer but it looks exactly like this. Does it not make any sense?

Hero · Answer

Well, use the draw tool to draw what's on your computer screen.

There was a unit circle... which is where the information came from.

Hero · Answer

Oh I see. I thought you were posting information given in a triangle.
