Introduction to Vectors | Finding the Magnitude of a Vector | Direction Angle of a Vector

http://www.greenemath.com/ In this lesson, we will learn about vectors and show how to find the magnitude of a vector, along with how to find the direction angle of a vector. A vector is just a directed line segment, it has a magnitude or length and a direction shown by the arrowhead or given as the direction angle. 0:00 Introduction 0:09 What is a vector 0:36 Vector notation 2:02 Comparing two vectors 3:09 Component form of a vector 4:44 Formula to find the magnitude of a vector 6:15 Finding the direction angle 7:11 Finding the magnitude and direction angle example #1 11:16 Finding the magnitude and direction angle example #2 13:24 Finding the component form, magnitude, and direction angle example #1 19:17 Finding the component form given magnitude and direction angle example #1 22:50 Finding the component form given magnitude and direction angle example #2
