Second Order Derivatives & Stationary Points (and Fermat's Theorem?)

What are second order derivatives? What are stationary points? This video answers these questions and goes through two examples to help you better understand these concepts. Did you know there is a theorem named after Fermat related to stationary points? It's one of the few theorems named after him! https://www.technologyuk.net/mathematics/differential-calculus/fermats-theorem.shtml ❤️ ❤️ ❤️ Support the channel ❤️ ❤️ ❤️ https://www.youtube.com/channel/UCf89Gd0FuNUdWv8FlSS7lqQ/join
