Best ResponseYou've already chosen the best response.0x/r = cos(theta) y/r = sin(theta) r^2 = x^2 +y^2 have you made those substitutions?

Best ResponseYou've already chosen the best response.0r= 2x/r + 3 y/r ...........> r2=2x+2y .. ...............> x2 + y2= 2x + 3y > x22x3y+y2= 0... is it correct¿?

Best ResponseYou've already chosen the best response.0you can clean it up a bit by completing the square on both the x and y terms.. eg.: (x^2 2x) = (x^2 2x +1) 1 = (x1)^2 1
