Limits and ContinuityThe idea of limits is central to all of calculus. For example, the derivative is defined using a limit, and the definite integral can be calculated using limits as well. There are several theorems rega...
Thus, the domain of f(x,y,z) is {(x,y,z):x+y+z>0}, which means f(x,y,z) is continuous on and above the z=–x–y.Perfect!Together we will expand upon our knowledge of limits and continuity. We will use the delta epsilon proof to discover how to evaluate a limit of a ...
very little research describing the concept of limit in multivariable calculus. In this paper, I begin the process of creating such a description of how students may reason about multivariable limits and how reasoning about multivariable limits may impact their understanding of the ...

This technique is immensely useful for both single-variable limits and multidimensional limits. A comprehensive treatment of multidimensional limits and continuity is also outlined.doi:10.1080/0020739X.2012.742148EleftheriosDepartmentGkioulekasDepartmentInternational Journal of Mathematical Education in ence and ...
In calculus, 0/0 is sometimes used as a symbol, and is called an indeterminate form, but the symbol does not represent division in the sense the word is used in ordinary arithmetic. Another common operation that is undefined is that of raising zero to the zero power. On the one hand, ...
sure, we can establish the continuity of some functions without too much trouble, and as long as we stay in that little family of functions, we can forget about how we established they were continuous in the first place (the "only need to prove something once motto"). but even with func...
