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.
