Geometry 8.6a, Vectors, component form, magnitude, direction
1K views on YouTube
An introduction and explanation of vectors, and component form as the horizontal and vertical change from the initial point to the terminal point. We see how to write vectors in component form, discuss the magnitude of a vector as its length, we use the distance formula to find the magnitude of a vector, the direction of a vector is the angle that it makes with a horizontal line, how the direction of a vector can be given as a bearing that is relative to compass directions, zero vector, finding the direction of a vector as an inverse tangent, and vector notation that we will be using.
