題目:An orthogonal (u.v.z)coordinate system is defined by the following

set of equations that these cooordinates to a "standard" Cartesian set:

                u =  x/(x^2 + y^2)

                v = -y/(x^2 + y^2)

                z = z

sktch the lines of constant u and constant v in the xy-plane

想請問各位要如何解題，如何做圖，謝謝各位。
