plane curve[′plān ‚kərv]
a curve whose points are all coplanar. It can be defined analytically by means of Cartesian or polar coordinates. In Cartesian coordinates it can be given in implicit form, F(x, y) = 0; in explicit form, y = f(x); or in parametric representation, x = ɸ(t) and y = ψ(t). The polar representation is ρ = f(ɸ).
