Interactive Tutorial: Root Finder

Interactive tutorials may be easily designed to explain simpler facts from numerics or geometry. They may be made available to students online as the supplemental material of classical university and high school courses. Additional to other course notes the students may regularly look at web pages accompanying the current course. Distant learning projects must have well prepared course materials since the direct contact with students is less intensive. These projects will be among the first to include interactive experiments, and maybe even the driving forces for the development of whole packages of interactive online experiments.The applet demonstrates the numerical algorithm of finding the zero-crossings of functions. The method subdivides the original interval and uses Brent's method to find the roots on each subinterval. Here, the user is assumed to read a description of the algorithm and simultaneously study the online example.
