Examples For How to Find Directional Derivatives (Calculus 3) ➡️ Download my FREE Multivariable Functions Cheat Sheets: https://www.jkmathematics.com/multivariable-cheat-sheets 🖥️ Membership Site (community & bonus content): https://www.jkmathematics.com/plus 🌐 My Website: https://www.jkmathematics.com ⭐️ Support Me on Patreon: https://www.patreon.com/JKMath In this video we practice finding directional derivatives. This includes examples where we use given angles, vectors, or points related to the direction in which we want to find the derivative/slope at a point on a surface. This video series is designed to help students understand the concepts of Calculus 3 at a grounded level. No long, boring, and unnecessary explanations, just what you need to know at a reasonable and digestible pace, with the goal of each video being shorter than the average school lecture! Calculus 3 requires a solid understanding of concepts from calculus 2, calculus 1, precalculus, and algebra. This includes limits, differentiation, advanced integration techniques, applications of derivatives and integrals, polar coordinates, parametric equations, trigonometric functions, logarithms, factoring, equation manipulation, graphing, and much more. If you are not familiar with these prerequisite topics, be sure to learn them first!
