In Summary
One-sided limits are a type of mathematical concept defined as the limit of a function as it approaches a certain value from one direction, either from the left or the right. In order for a limit to exist at a point, both the left and right limits must be the same. One of the main reasons we learn about one-sided limits is because for a lot of functions, the left limit doesn’t always equal the right limit.
One-sided limits are typically introduced in calculus courses.
One-sided limits were first formally introduced by Augustin-Louis Cauchy in the early 19th century.
