Assume that we are given with ϕ = 60^o while ρ and z coordinates can take any value.
So, just apply the definition of ϕ coordinate. It is the angle made by the vertical half plane containing the given point with +X.
So obviously, all the points which are present on the same vertical half plane, would have same ϕ coordinate i.e. ϕ = 60^o. In other words, locus of ϕ = 60^o will be the vertical half plane.
So, locus of ϕ = constant is a vertical half plane stuck to the Z – axis making an angle ϕ with the +X axis.
