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).
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
USC students can use their USC Network username and password
to access this secure site.
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.
