Pick and drag new initial point in the viewer window. This modifies the
initial x and y values. Initial values of higher
derivative of y can be modified inside the text field Initial
y.

Type a new differential equation. Whenever you type in a text field press enter
to submit your changes. Use keyboard key i to switch back to mode
allowing picking of initial values:
| i |
pick initial x and y
values |
The integrator is a fourth-order Runge-Kutta method with constant step
size.
Controls in ODE project panel:
| ODE text field |
Type a new ordinary differential equation. Higher
derivatives of y must be denoted dy, d2y or d3y.
In this text field you can use all mathematical functions shown in list of function expressions. |
| Text field "Order" |
Defines the order (highest derivative of y)
of the differential equation |
| Slider "Step Size" |
Discretization for x-values |
| Slider "Length" |
Length of the x-interval to evaluate the
differential equation. |
| Slider "Initial x" |
Minimum value for x-interval |
| Text fields "Initial y" |
The first text field shows the initial y-value,
the second text field shows the initial value of the first derivative of y,
if "Order" is greater than 2, further text fields for the
higher derivatives are displayed. |
