Hi. When we say that [itex]\displaystyle \lim_{n \to \infty}f_n(x)=g(x)[/itex], do we mean that [itex]f_n[/itex] is pointwise or uniformly convergent to [itex]g[/itex]?
Thanks.
Thanks.

The limit of a sequence of functions is a mathematical concept that describes the behavior of a sequence of functions as the input values approach a certain value or approach infinity. It is denoted by the notation lim f(n), where n represents the input values and f(n) represents the sequence of functions.
The limit of a sequence of functions is calculated by evaluating the behavior of the sequence of functions as the input values approach the given value or infinity. This can be done by plugging in values that are closer and closer to the given value and observing the corresponding output values. If the output values approach a certain value or tend towards a specific trend, then the limit of the sequence of functions can be determined.
The limit of a sequence of functions is important in many areas of mathematics, including calculus, analysis, and topology. It allows us to study the behavior of functions as the input values approach a certain value, which is crucial in understanding the continuity and convergence of functions. It also helps in determining the behavior of infinite series and integrals.
Yes, the limit of a sequence of functions can be infinite. This happens when the output values of the sequence of functions approach infinity as the input values approach a certain value or infinity. In such cases, the limit is said to be an infinite limit.
The concept of the limit of a sequence of functions is closely related to the concept of a limit of a function. The main difference is that the limit of a sequence of functions deals with the behavior of a sequence of functions as the input values approach a certain value or infinity, while the limit of a function deals with the behavior of a single function as the input values approach a certain value. Both concepts are fundamental in understanding the behavior and properties of functions in mathematics.
