Line integrals, two or three variables. When the domain of such functions is a region of a space, we usually refer to the functions as .. Thus, a vector field is a rule which associates a vector with each point in a region of space. In this usage, we could refer to a function of two or three variables as a ..

You should be aware that we are working with exact numbers and algebraic expressions. None of the exercises need a calculator and using one may obscure the point being covered.

Functions of two variables, of a function of one variable, we define a function . of two variables, . and ., say, by its value at all points of the domain. Thus the domain has to be described in terms of both variables . and .. The following definition enables us to do this.
