We know about vectors, and we know about functions, so we are ready to learn about vector fields. These are like functions that take in coordinates and give back vectors, so there will be a vector associated with every single point in the field. There are two things we must be able to do with vector fields as well, which involve the del operator and either the dot product or the cross product with the vector field. These give us the divergence and the curl of the vector field, respectively. Let's learn all about these operations now.
