The equation button allows you to input the differential, intial values, step size (possibly 2nd step size) and iterations (number of times to run the method).

The points button displays all the points found with Euler's method.

Point mode draws circles to indicate graphically all the points found with Euler's method.

This program supports all well known math functions and constants. Shown below are some example functions to input:

`x^3+2x+3`

`e^x`

`sqrt(x)/cbrt(y)`

`tan(x)`

`atan(x)tanh(x)atanh(x)`

`abs(x/y+y/x)`

`log(x,e)`

`x > 0 ? x^2 : x mod 10`
