We learn about free, sliding, and fixed vectors. We then look at different types of vectors - unit, zero, equal, opposite, collinear, and co-initial.

We derive the formula for the magnitude of a position vector. We look at a few lazy ways to talk about direction of a vector before talking about the direction cosines. We also discuss why cosines are better at this than sine or tan.

For reference, we use unit vectors along x, y, and z axes and represent the vectors in terms of sums of multiples of these unit vectors. We also represent a vector between two points. We solve a few problems to get familiar with the notations. Finally, we look at a few properties of algebra of vectors.
