I've written another small TurboBasic program.

 

(boot the atr and load"d:desys.tbb"

 

You can enter a so called system of "differential equations" in line 110 & 120

 

Then run and some curves are drawed, according to the given equations.

 

F.e.

 

110 DFX=FY

120 DFY=-FX

gives circles

 

in line 10 and 20 you can adjust some parameters:

 

SC changes the scaling factor of the picture (Defaults: 25 or 10)

HH changes the step size of the "Euler-forward" approximation algorithm (Defaults: 0.05 or 0.1)

 

another example

 

110 DFX=FY-1

120 DFY=-FX*FY

 

or

 

110 DFX=-FY-1

120 DFX=-FX*FY

 

When there's no action (f.e. when a curve converges to a point of equilibrium) press START to continue on a next curve.
