Direction Cosines Examples | Calculus 3 - JK Math

Examples For How to Find Direction Cosines & Angles (Calculus 3)

In this video we look at example problems involving direction cosines and angles. This includes finding directions cosines & angles, showing that the sum of squares of direction cosines is 1, and using direction cosines to represent the direction of a position vector with a unit vector.

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!
