Energy of magnetic dipole: U = -mB Energy of electric dipole: U = -pE (potential energy is minimal when aligned with field work done given by W=Fd
Gauss Theorem
div . D = ro (electric displacement and charge density) this integrated over a volume should give the charge

conversion between coordinate systems
reexpressing the position in the new coordinates converting the unit vectors for differential operators: expressing the operators in the new basis system (may affect unit vectors) for integration: converting the limits and…
Gibbs Phenomenon
first few terms of fourier series overshoot the value for small n For larger n the overshoot does not disappear but the position of each overshoot has moved closer to the discontinuity.
Stoke’s Theorem
The curl of a vector field integrated over any surface is equal to the contour integral over the boundary of the surface.
