Divergence of Spherical Coordinates

Click For Summary
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.

Homework Statement



Compute the divergence of v = (1/(r^2)) r where r = sin(u)cos(v)i + sin(u)sin(v)j + cos(u)k, r^2 = x^2 + y^2 + z^2


The Attempt at a Solution



I can only think to express r as a function of x,y,z and do it. I know there's a simpler way though, but it's driving me crazy. I can't find anywhere how to do this.
