Origin and evolution of ‘primitive’ warfaref referring to . and . separately, we shall often refer to them as a point (.); then we can talk about . being evaluated at the point (., .), while the domain of . is the rectangle in the . plane defined by the above inequalities.

Vectors,esults to a practical situation, we usually find it necessary to describe the vectors in terms of their coordinates. For this reason, as well as to ease the derivation of algebraic rules for vectors, we start with a brief study of coordinate systems.

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

Functions of Two Variables,ion. We now turn to functions of two variables, where the values of . variables must be given before we can evaluate the function. As in the case of a function of one variable, we define a function . of two variables, . and ., say, by its value at all points of the domain. Now, however, ranges of va
