This is a list of limits for common functions such as elementary functions. In this article, the terms a , b and c are constants with respect to x . Limits for general functions
Since e is an irrational number (see proof that e is irrational), it cannot be represented as the quotient of two integers, but it can be represented as a continued fraction. Using calculus, e may also be represented as an infinite series, infinite product, or other types of limit of a sequence.
Augustin-Louis Cauchy in 1821, [6] followed by Karl Weierstrass, formalized the definition of the limit of a function which became known as the (ε, δ)-definition of limit. The modern notation of placing the arrow below the limit symbol is due to G. H. Hardy , who introduced it in his book A Course of Pure Mathematics in 1908.

If the one-sided limits exist at p, but are unequal, then there is no limit at p (i.e., the limit at p does not exist). If either one-sided limit does not exist at p, then the limit at p also does not exist. A formal definition is as follows. The limit of f as x approaches p from above is L if:
3Blue1Brown is a math YouTube channel created and run by Grant Sanderson. [6] The channel focuses on teaching higher mathematics from a visual perspective, and on the process of discovery and inquiry-based learning in mathematics, which Sanderson calls "inventing math".
Nearly $3.6 billion Canadian (US $2.7 billion) worth of goods and services cross the border each day. About 60% of U.S. crude oil imports are from Canada, and 85% of U.S. electricity imports are ...
This limit can be shown to exist for any , and it defines a continuous increasing function () = with () = and () =, so the Intermediate value theorem guarantees the existence of such a value =. Equivalence of the characterizations
