• the function f(r) is a constant, e.g., unity, then one sees that the delta is normalized.

As a result, it In spherical polar coordinates: ξ1 = r, ξ2 = θ, ξ3 = ϕ, we have. The three-dimensional delta function must satisfy: in cylindrical coordinates: \delta^3(\rr-\rr_0) = {1\over r}. Use the identity δ(f(x))=δ(x−a)/|f′(x)|, where a is a root of f, and apply it to the case for f(x)=cosθ−cosθ0.

To show that this works, observe the integral.
