A visualisation of a solution to the two-dimensional heat equation with temperature represented by the third dimension. Just as ordinary differential equations often model one-dimensional dynamical systems, partial differential equations often model multidimensional systems. If the equations are overlapping the text (they are probably all shifted downwards from where they should be) then you are probably using Internet Explorer 10 or Internet Explorer 11. PDEs are used to formulate problems involving functions of several variables, and are either solved by hand, or used to create a relevant computer model. Alternatively, you can view the pages in Chrome or Firefox as they should display properly in the latest versions of those browsers without any additional steps on your part. A special case are ordinary differential equations (ODEs), which deal with functions of a single variable and their derivatives. In mathematics, a partial differential equation (PDE) is a differential equation that contains unknown multivariable functions and their partial derivatives.

Wiley E-Texts are accessible online and offline, and can be read on a variety of devices, including smartphones and tablets. PDEs can be used to describe a wide variety of phenomena such as sound, heat, electrostatics, electrodynamics, fluid dynamics, elasticity, or quantum mechanics. Click on this and you have put the browser in Compatibility View for my site and the equations should display properly. Most of the classes have practice problems with solutions available on the practice problems pages. Look to the right side of the address bar at the top of the Internet Explorer window. Navierâ€“Stokes differential equations used to simulate airflow around an obstruction. Also most classes have assignment problems for instructors to assign for homework (answers/solutions to the assignment problems are not given or available on the site).

E-books have DRM protection on them, which means only the person who purchases and downloads the e-book can access it. My Students – This is for students who are actually taking a class from me at Lamar University.
