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. Living Example Problems POLYMATH software that allows students to explore ttie. (5.572) and (5.575)) can be solved only by numerical methods, e.g. The total pressure drop is evaluated by the general model (case 1), i.e. I SoivB system ol Oninaty Differ ilial Equations I File Program Edit Format Problem Examples Window Help Ĭonsider the following reaction taking place in a batch reactor Templates are available that allow easy problem solution in MATLAB that can be very helpful for novice or experiences MATLAB users.Fit a set of experimental data using the regression option using the REG option. Polymath automatically translated the problem into ordered equations in MATLAB code. MATLAB users will appreciate POLYMATH's ability to provide a problem solution in a format that can directly be incorporated into “m” files. Automatic problem export from Polymath to Excel includes the conversion of all intrinsic functions and logical variables. A POLYMATH ODE_Solver Add-In is included and allows for the solution of ordinary differential equations in Excel. Thus problems can be solved completely in Polymath or exported to Excel for solution. Version 6.1 provides the new and UNIQUE capability to automatically export any POLYMATH problem to Excel with a single keypress. POLYMATH has a minimal learning curve and provides extensive error checking during problem entry that leads to great efficiency in problem solution. Graphical and tabular results are provided for easy understanding and for incorporation into papers and reports. POLYMATH enables the user to apply effective numerical analysis techniques during interactive problem solving on personal computers.
