Nettet2 Answers Sorted by: 2 You need consider paths on the x y -plane as follows: If a limit exists, then it must approach the same value no matter what way you approach ( 0, 0). Consider the first example. If you take a line y = x and approach ( 0, 0) along that line, you get, lim ( x, y) → ( 0, 0) x 9 y ( x 6 + y 2) 2 = lim x → 0 x 10 ( x 6 + x 2) 2 NettetWhenever we have multiple variables involved, look for the interval that the variables are in, and we'll able to find a bound (upper or lower) for the variables. For example, in your example, the interval for (x,y) is (1,2). Thus, I claim x < 1 and y < 2 respectively, and note the inequality are strict, since this interval is not closed. highway 1 hope to chilliwackNettetThe definition of a limit of a function of two variables requires the δ disk to be contained inside the domain of the function. However, if we wish to find the limit of a function at a boundary point of the domain, the δdisk is not contained inside the domain. highway 1 hotels
