Review of Differential Calculus
William P. Fox · 2020
The idea of a limit is one of the most basic ideas in calculus. The equation lim x → a f ( x ) = c https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003009573/2392ac59-6ff7-4ff6-9c3a-6f5b9c04915c/content/C002_equ_0001.tif"/> means that as x gets closer to a (but not equal to a ), the value of f ( x ) gets arbitrarily close to c . It is also possible that the lim x → a f ( x ) https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003009573/2392ac59-6ff7-4ff6-9c3a-6f5b9c04915c/content/C002_equ_0002.tif"/> will not exist. Limits can be viewed analytically, graphically, and by numerical tables.
