If f and g are real-valued (or complex-valued) functions, then taking the limit of an operation on f(x) and g(x) (e.g., f + g, f − g, f × g, f / g, f g) under certain conditions is compatible with the operation of limits of f(x) and g(x). This fact is often called the algebraic limit theorem. The main condition needed to apply the following ...

While this is often shown using the mean value theorem for real-valued functions, the same method can be applied for higher-dimensional functions by using the mean value inequality instead. Interchange of partial derivatives: Schwarz's theorem; Interchange of integrals: Fubini's theorem; Interchange of limit and integral: Dominated convergence ...
According to the uniform limit theorem, if each of the functions ƒ n is continuous, then the limit ƒ must be continuous as well. This theorem does not hold if uniform convergence is replaced by pointwise convergence. For example, let ƒ n : [0, 1] → R be the sequence of functions ƒ n (x) = x n.
Since taking different paths towards the same point yields different values, a general limit at the point (,) cannot be defined for the function. A general limit can be defined if the limits to a point along all possible paths converge to the same value, i.e. we say for a function : that the limit of to some point is L, if and only if
In multivariable calculus, an iterated limit is a limit of a sequence or a limit of a function in the form , = (,), (,) = ((,)),or other similar forms. An iterated limit is only defined for an expression whose value depends on at least two variables. To evaluate such a limit, one takes the limiting process as one of the two variables approaches some number, getting an expression whose value ...
