# Ordinary Differential Equations Math 520 -- Section 001, Fall 2011

## Additional Resources

• Calculus Review Sheet -- prepared by Prof. Maria Girardi's webpage for MATH 142
• Direction Field Plotter A Java applet for plotting direction fields, solution curves, and isoclines. A version for offline use is also available.
• Direction Field Plotter This Java applet will display the phase portrait for any 2x2 system of differential equations. Specify the equation in the boxes below the graph and click New Function to see the field. To see the solution curves through a specific point, click on that point in the phase portrait. Click on lots of points if you wish. For some problems you will want to change the viewing window (see the boxes along the right edge of the window, and click Set Limits).
• Ordinary Differential Equations Resources An archive of electronic resources related to the teaching of ODEs.
• Maplets for Calculus A collection of maplets for topics in single-variable calculus. Students in differential equations will find practice working with separable and first-order linear ODEs as well as drill-and-practice for Substitution, Integration by Parts, and general integration techniques. USC students can use their USC Network username and password to access this secure site.
• ODE PowerTool [HTML] [Maple Worksheet] , a collection of 35 Maple worksheets for an introductory course in differential equations. Archived at Maplesoft's Maple Application Center / Education PowerTools / Differential Equations at the URL http://www.maplesoft.com/applications/app_center_browse.aspx?CID=14&SCID=120.
• dfield - a public-domain web-based tool for drawing direction fields
• http://www.webgraphing.com/ - collection of web-based graphing calculators
• http://integrals.wolfram.com - free symbolic integration interface

Notes:

• Maple worksheets (.mw files) should be downloaded to your local computer. (I recommend creating a folder to hold all of these files, say, MATH520-Maple-files.) Once downloaded, a worksheet can be opened by double-clicking.
• Maple is available on many computers on the USC campus. If there is a university-owned (or leased) computer where you want to use Maple that does not have a copy of Maple installed on it, let me know and I will try to work with the appropriate people to have Maple installed on that computer.
• Students in this course can obtain a copy of Maple through the Maple Adoption Program. If you are interested in this, browse to the Maple webstore. Prior to checking out, be sure to enter the code: UOSC-0909 to ensure that you get the special pricing for USC students.
• Portable Document Format (PDF) files are viewable with acroread, a publicly available PDF viewer by Adobe.
