The "Limit of a Function" part is barely intelligible , IMO
The concept of the limit is a cornerstone of the mathematical branch of [[analysis]].
==Limit of a Sequence==
Let <math>(a_n)_{n\in N} = (a_1, a_2, a_3, ...)</math> be a [[sequence]] of real numbers. We say that this sequence has a limit <math>a</math>, i.e.,
<math>
\lim_{n\to \infty} = a,
</math>
if for any <math>\epsilon > 0</math>, there exists a number <math>N</math>, such that
<math>
|a_n - a| < \epsilon</math> for every <math>n > N</math>.
==Limit of a Function==
Let <math>f(x)</math> be a real valued [[function]] in one [[variable]]. We say that
