We are now in a position to express -r as a function of X and use the techniques in Chapter 2. The predator-prey relationships are given by the following set of coupled ordinary differential equations. Use Polymath or MATLAB to plot the concentration of foxes and rabbits as a function of time for a period of up to 600 days. (a) There are initially 400 rabbits (x) and 200 foxes (y) on Farmer Oat s property.

Infonnation on how to obtain and load the Polymath Software is given in Appendix E and on the DVD-ROM. Hiese equation solvers will be used extensively in later chapters. Tliis problem focuses on using Polymath, an ordinary differential equation (ODE) solver, and also a non- linear equation (NLE) solver. Students, engineers, mathematicians, scientists, or anyone with a need to solve problems will appreciate the elSciency and speed of problem solution. Results are presented graphically for easy understanding and for incorporation into papers and reports. The various POLYMATH programs allow the user to apply effective numerical analysis techniques during interactive problem-solving on personal computers.

POLYMATH (http //is a proven computational system, which has been specifically created for educational or professional use. One-dimensional tests from the Web site are implemented in C++ and adopted to validate the BzzFunctionRootRobust class. (2002) presented a set of nonlinear systems from one- and multidimensional chemical engineering problems. Tlie conversion of ppm into mol/m is done by using the molai weight of CO (28 kg/kmol) and the density of air (1.09 kg/nri). Note that T is in K and that the concentration of CO is in moPnri. The solutions ai e only aiithmetic and Polymath software has been used. This weh site provides information on how to obtain an iqxluted version of Polymath at a discount. A special Polymath web site tniler) has been set up f(ar this book by Polymath authors Cutlip and Shacham. Polymath is included with this ediiion to explore the example problems and to solve the home problems. The Polymath software includes an ordinary differemial equation (ODE) solver, a nonlinear equation solver, and nonlinear regression. Here we first choose the polynomial degree (in this ease, fourth degree) an then type in the values of at various limes t to obtain. We will use the Polymath software package to express concentration as a funciic of time. The companion CD-ROM provides additional learning resources such as sumniai notes, interactive computing modules, web modules, POLYMATH software to explore Tiviag example problems and ask what-if questions, and many more enrichment opportunities for both students and teachers. These estimates can be obtained using the linear-least-squares technique just discussed. In order to cany out the search efficiently, in some cases one has to enter initial estimates of the parameter values close to the actual values.

The POLYMATH software will be used to illustrate this technique. Many software programs are available to find these parameter values and all one has to do is to enter the data. In nonlinear least squares analysis we search for those parameter values that minimize the sum of squares of the differences between the measured values and the calculated values for all the data points.
