How to understand the limit:

The meaning of limit:

Explanation of words:

1.? Maximum. Example: the limit of a person's patience.

2.? When the value of the independent variable approaches infinitely but is not equal to a specified value, or increases to a certain extent in the positive or negative direction, the difference with the numerical value of the mathematical function is infinitesimal.

Interpretation by reference:

1. Maximum.

Quote:

Network explanation:

Limit (mathematical term).

"Limit" is the basic concept of calculus, a branch of mathematics. The "limit" in a broad sense is "infinitely close and never reached".

"Limit" in mathematics refers to a variable in a function.

The change of this variable in the process of getting bigger (or smaller) and approaching a certain value A, and "it can never coincide with A" ("it can never be equal to A, but taking a value equal to A' is enough to obtain high-precision calculation results).

It is artificially defined as "always approaching", and it has a "trend of approaching point A". Limit is a description of "changing state". The value a that this variable always approaches is called the "limit value" (of course, it can also be expressed by other symbols).

The above is a popular description of the connotation of "limit", and the strict concept of "limit" is finally strictly expounded by Cauchy and Weisstras.
