In the Single Variable Calculus course, Professor Gross discussed the calculus of a single real variable in which the domain of a function was a subset of the real numbers.Now, in the language of vectors, a function maps 2 and 3 dimensional vectors into the set of real numbers.He then uses these functions to show how we compute the velocity and acceleration of an object moving in space.
