Solves boundary-value or initial-value problems
involving nonlinear or linear ordinary differential
equations of any order, or systems of such. The
conditions may also be linear or nonlinear equations
involving the unknown functions and their
derivatives. The solution produced is a continuous
function in the form of finite power or trigonometric
series, depending on the program, of user-specified
number of terms valid in the entire defined interval
and expanded about a user-chosen center of expansion.
Results, including the graph, can be saved or
printed. You can also copy the graph to the
clipboard, which you can then paste where you please
(Word, Paint, etc.). You have one-click control of
the graph with zooming, panning, centering, etc. The
solution may be stored in a file which may be later
read by a suitable program (like POWER AND
TRIGONOMETRIC SERIES) to further study it to find
roots, maxima and minima, derivatives, integral,
graph. You can predefine any recurring constants.
Handles a wide variety of functions, including
trigonometric and hyperbolic. Results can be saved or
printed. Includes a help file with instructions,
examples and methodology.
