WebMay 6, 2003 · div grad &phi = 0 and curl grad &phi = 0 So the degrees of freedom in the original equation is precisely the set of gradients of solutions to Laplace's equation. As to the proof that any solution exists, I'm going to cheat and say look at Wolfram for an explicit formula. http://mathworld.wolfram.com/HelmholtzsTheorem.html WebQ1. If î‚ ĵ and k̂ are unit vectors along X, Y and Z axes respectively, then the product (î × ĵ) will be equal to: Q2. If a → and b → are unit vectors and θ is angle between them, then …

Hence the surface integral over the whole S will be zero, and the volume integral of div curl F is zero, too. Since we can change the radius and position of the sphere at will, div curl F must be zero. curl grad phi can be proved similarly, and many people have pointed out clear interpretations. lpk artistryWebFeb 5, 1997 · (3) Phi(x) = - G d x' -------- , x - x' / where Gis the gravitational constant and the integral is taken over all space.
