More on unit vector notation. Showing that adding the x and y components of two vectors is equivalent to adding the vectors visually using the head-to-tail method. This video, which is suitable for high school students, starts with a black screen bec...ause the instructor, in his conversational tone, uses it as a 'chalkboard.' Instructor uses different colors for clarification. (09:13)[more]

This visually confusing tip-to-tail vector addition problem can be solved just like our previous problems. Give your vectors names, draw a vector diagram, break vectors in to components, redraw the vector diagram, create a data table, add columns an...d solve using basic trig.
