Polynomial Roots

This worksheet illustrates how the roots of a polynomial affect its behavior. Below is a plot of the polynomial
px = x-a x-b xn-2, where n is the degree of the polynomial and a and b are two real roots you can control with the sliders. Note that when the degree n is greater than two then zero is always a root of the polynomial.

Value of root a:
Value of root b:
Degree of polynomial:

With the advent of HTML5, Javascript is now ready for prime time for mathematical applications. There are new Javascript demos illustrating how we might use interactive web objects to help students learn Calculus.
