SUMMARY
The divergence of the vector field v = (1/(r^2)) r, where r is defined in spherical coordinates as r = sin(u)cos(v)i + sin(u)sin(v)j + cos(u)k, can be computed using the divergence operator in spherical coordinates. The divergence operator in spherical coordinates is given by the formula ∇·v = (1/r^2)(∂/∂r)(r^2 v_r) + (1/(r sin(u)))(∂/∂u)(sin(u) v_u) + (1/(r sin(u)))(∂/∂v)(v_v). This approach simplifies the computation compared to converting r into Cartesian coordinates. Understanding this method is essential for efficiently calculating divergence in spherical systems.
