Numerical Solution of Differential EquationsLiz BradleyDepartment of Computer ScienceUniversity of ColoradoBoulder, Colorado, USA 80309-0430c 1998 Revised versionc 2002, Report on Curricula and Teaching CT003-981 Ordinary Differential EquationsA differential equation expresses a set of constraints amongthe derivatives of an unknown function. Here s asimple example:ddtx(t) =ax(t)(1)What this means is that the derivative of the unknown function is equal toatimes the unknown function compactness, the independent variable (t, here) is often omitted and the notationdxdtis often abbreviatedwith a dot, like so: xor with a prime, like so:x.
Differential equations are interesting and useful to scientists and engineers because they “model” the physical world: that is, they capture the physics of a system, and their solutions emulate the behavior of that ... A 3D plot of all three pieces of the solution against one another — with x(t) on the x axis, y(t) on the y axis, and z(t ...
