Показать описание
In this video, we demonstrate how to find all four complex roots to a biquadratic polynomial using the method of complex roots.

This lecture is based upon general college trigonometry curriculum and not based upon an individual textbook. With that said, this lecture series is influenced by many great trigonometry textbooks on the market, namely Sullivan's, Stewart's, OpenStax's, McKeague's, Stitz-Zeager's, and many others. Please post any questions you might have below in the comment field and Dr. Misseldine (or other commenters) can answer them for you. Please also subscribe for further updates.
