Explanation: Enter the ordinary differential equation that needs to be solved in the field y'=f(x,y). The usual math function can be used: +.-.*,/,(,), abs(), acos(), asin(), atan(), atan2(), cos(), exp(), log(), pow(), sin(), sqrt(), tan(). Note for something like y^3 used the pow(y,3) notation.
Type in the interval range in x= and set the initial conditions in Initial y(x₀). Finally select how many intervals that should be subidvided in the x interval specified. Select one or more methods you like to use or compare solving the ordinary differential. Checkmark the Verbose print out details for each interval step.

The tab (Graphing) graph the equations in the interval given. The Test button setup a default differential (for testing only).
