13.2 Limits and Continuity Contemporary Calculus 2 All of the limit properties in the Main Limit Theorem (Section 1.2) are also true for limits of functions of two variables, and many limits of functions of two variables are easy to calculate. Example 1: Calculate the following limits: (a) lim (x,y)!(1,2) xy x2+y2 (b) lim (x,y)!(0,2) cos(xy2 ...

PART A: THE LIMIT OF A FUNCTION AT A POINT Our study of calculus begins with an understanding of the expression lim x a fx(), where a is a real number (in short, a ) and f is a function. This is read as: “the limit of fx() as x approaches a.” • WARNING 1: means “approaches.” Avoid using this symbol outside the context of limits ...
Limits are a very powerful tool in mathematics and are used throughout calculus and beyond. The key idea is that a limit is what I like to call a \behavior operator". A limit will tell you the behavior of a function nearby a point.
First, we formally define the limit of functions. Definition 1 Let f : X 7→R, and let c be an accumulation point of the domain X. Then, we say. f has a limit L at c and write limx→c f(x) = L, if for any > 0, there exists a δ > 0 such that. 0 < |x − c| < δ and x ∈ X imply |f(x) − L| < . A few remarks about this definition are worthwhile.
