Vectors

This precalculus video tutorial explains the basics of vectors. It contains plenty of examples and practice problems of vector operations such as addition, subtraction and scalar multiplication as well as finding the magnitude and direction angle of the resultant force vector. This video is useful for high school and college students taking vectors in precalculus, calculus, physics, or trigonometry.
