WebMay 15, 2016 · I have to study this limit when x and y tends to (0,0) \displaystyle f (x,y) = sin (xy)/ (xy) f (x,y)= sin(xy)/(xy) Aproximating the limit I get that it exists. However, I don't know how to calculate it. Are you able to refer at all to the basic trig limit you learned back in first-semester calculus? WebLimits, a foundational tool in calculus, are used to determine whether a function or sequence approaches a fixed value as its argument or index approaches a given point. Limits can be defined for discrete sequences, functions of one or more real-valued arguments or complex-valued functions. For a sequence {xn} { x n } indexed on the natural ... how to crayon etching

WebDec 28, 2024 · Example 12.2.2: Determining open/closed, bounded/unbounded. Determine if the domain of f(x, y) = 1 x − y is open, closed, or neither. Solution. As we cannot divide by 0, we find the domain to be D = {(x, y) x − y ≠ 0}. In other words, the domain is the set of all points (x, y) not on the line y = x.
