A detailed tutorial of solving Dirichlet problems. Step by step tutorial including several examples of how to solve Dirichlet problems for reference.
Overview
A Dirichlet problem is a problem of finding a function which solves a specified partial differential equation in the interior of a given region that takes prescribed values on the boundary of the region. It was originally supposed to be used for Laplace’s equation, although other equations can use it as well. The Dirichlet problem can be stated as: given a function f that has values everywhere on the boundary of a region in R^n, is there a unique continuous function u twice continuously differentiable in the interior and continuous on the boundary, such that u is harmonic in the interior and u = f on the boundary? A mathematical solution can be expressed as:

A detailed tutorial on simple harmonic motion. Step by step tutorial including several examples of simple harmonic motion for reference.
Overview
Simple harmonic motion is related to Hooke’s law – as what Hooke’s law does is measure harmonic motion. Simple harmonic motion is motion that is neither driven nor damped. It is one movement, one force. This motion can also be periodic. Simple harmonic motion is expressed by the equation:
