This clips shows how to solve a simple differential equation in MathCad. I show how to solve an initial value problem using the Odesolve command in MathCad and then solve it again using a finite difference approximation. Along the way, I show how the solution to the equation is just a specific path through a vector field. The path taken by the solution is defined by the initial value.

How to solve the heat equation on the whole line with some initial condition. Suppose one has a function u that describes the temperature at a given location (x, y, z). This function will change over time as heat spreads throughout space. The heat equation is used to determine the change in the function u over time. The rate of change of u is proportional to the "curvature" of u. Thus, the sharper the corner, the faster it is rounded off. Over time, the tendency is for peaks to be eroded, and valleys filled in. If u is linear in space (or has a constant gradient) at a given point, then u has reached steady-state and is unchanging at this point. One of the interesting properties of the heat equation is the maximum principle that says that the maximum value of u is either earlier in time than the region of concern or on the edge of the region of concern. This is essentially saying that temperature comes either from some source or from earlier in time because heat permeates but is not created from nothingness. This is a property of parabolic partial differential equations and is not difficult to prove mathematically (see below). Another interesting property is that even if u has a discontinuity at an initial time t = t0, the temperature becomes smooth as soon as t greater than t0. For example, if a bar of metal has temperature 0 and another has temperature 100 and they are stuck together end to end, then very quickly the temperature at the point of connection will become 50 and the graph of the temperature will run smoothly from 0 to 100. The heat equation is used in probability and describes random walks. It is also applied in financial mathematics for this reason. It is also important in Riemannian geometry and thus topology: it was adapted by Richard Hamilton when he defined the Ricci flow that was later used by Grigori Perelman to solve the topological Poincaré conjecture.

In this video, I describe how to use Green's functions (i.e. responses to single impulse inputs to an ODE) to solve a non-homogeneous (Sturm-Liouville) ODE subject to ANY arbitrary input f(x). All this involves is integrating the Green's function with the input f(x) over the domain. The input, by the way, is the function that makes the ODE non-homogeneous. This approach is made possible because of the orthogonality relation of the Sturm-Liouville Theorem and the fact that the eigenfunctions of a REGULAR Sturm-Liouville problem form a complete set. By the way, at 2:05, I say that we can make the eigenvalue 'any real number we want'. I should clarify that and say that we can make the 'n' in lambda_n 'whatever integer we want'. Lambda is still restricted by the boundary conditions. Nonetheless, the point that a smaller set of functions (eigenfunctions of a REGULAR Sturm-Liouville Problem) can be used to describe a larger set of functions (all nice/smooth functions) still holds. Questions/requests? Let me know in the comments! The oft-requested PDE version of my Green's Function video is coming out soon, so stay tuned! Prereqs: Know the Sturm-Liouville Theorem.
