Vectors: Notation, Operations, the Scalar Product, Lines and Skew Lines in 3DSign up
understand and use vectors in three dimensions, including position vectors, magnitude, unit vectors and the i, j, k basis · understand and use the scalar (dot) product a · b = |a||b| cos θ to find angles between vectors and to test for perpendicularity · be able to find the vector equation of a line in 3D, determine whether two lines are parallel, intersect or are skew, and find the angle between two lines
