Visualizing real roots of a high degree polynomial
( go to the article → https://www.johndcook.com/blog/2020/12/28/high-degree-polynomial/ )
The previous post looked at finding the expected number of real zeros of high degree polynomials. If you wanted to see how many real roots a particular high degree polynomial has, you run into several difficulties. If you use something like Descartes’ rule of signs, you’re likely to greatly over-estimate the number of roots. It […] The post Visualizing real roots of a high degree polynomial first appeared on John D. Cook.
