SUMMARY
Laplace's and Poisson's equations can be derived directly from Gauss's Law by manipulating the electric field and electric potential equations. To derive Laplace's equation, start with Gauss's Law in differential form, assuming no charge is present, and express the electric field in terms of electric potential. For Poisson's equation, follow the same steps but include a non-zero charge density, allowing for the relationship between charge distribution and electric potential to be established.
