Polynomial
The Polynomial tasks shows a fifth order polynomial generated from the five sliders. Each slider adjusts the coefficients of the following equation:
y = a x5 + b x4 + c x5 + d x2 + e x + f
The x variable is the independent variable and is plotted within the interval -1 to 1. Because x is limited to that interval taking its power produces a smaller value which helps bound y.
Plotting equations such as this are easy. If you would like a different equation (model) then email support@vvi.com.
