Calculator Programs
The three programs direction field, phase portrait,
and solution for second order equations may be used together to create
overlapping graphs. For example, conjectures from a direction field may
be tested by having a solution graphed through it.
Direction
field for TI-83.
Direction
field for TI-92.
Phase
portrait for TI-83.
Phase
portrait for TI-92.
Solution
second order equations for TI-83 - uses Runga-Kutta.
Solution
second order equations for TI-92 - uses Runga-Kutta.
