WebMar 27, 2015 · How do we determine the gradient and curl of a scalar/vector field in polar coordinates? For instance, if we have the following potential energy function for a force, U = k x ( x 2 + y 2) 3 / 2 it makes much more sense to compute the force in polar coordinates U = k cos θ r 2 But what is ∇ → ⋅ U in this case? The first thing that comes to mind is WebIn cylindrical coordinates, the gradient is given by Divergence of a tensor field [ edit] The divergence of a tensor field is defined using the recursive relation where c is an arbitrary constant vector and v is a vector field.
