[size=85]The intersection points of the curves are approximated as the intersection points of their corresponding polylines with [b]f[/b] segments. Numerical calculations result in many nearby intersections. Their filtering was done using the [url=https://www.geogebra.org/m/jktbxyec]applet[/url] method.[br] In this applet, unlike the following ones, the intersection objects are defined in the applet algebra. The applet loads faster and all changes are easily implemented when calculation objects of intersection are defined in the script rather than in the applet algebra.[/size]
