Newton's method
This interactive figure illustrates Newton's method up to 3 iterations.
Enter a function and an initial -value that you determine to be sufficiently close to a root (-intercept) of . Then, keep selecting the gray button to dynamically illustrate Newton's method, step-by-step. The last step of this interactive applet yields an approximate value of . This value will have pink color.
Note: You'll likely want to zoom and pan the graphics window along the way!
