If x is a cluster point for the sequence {x_n}, there is a subsequence of {x_n} whose limit is x. The subsequence can be constructed by choosing a sequence of shrinking neighborhoods V_k about x. Since x is a cluster point, each such neighborhood contains infinitely many elements of {x_n}. By choosing a new point x_k from each neighborhood V_k, we get a subsequence {x_k} of {x_n} with lim x_k = x.

Is there a limit to the number of lines that can intersect at one point?
No limit.
How many planes can intersect a line at a given point?
an infinite number; no limit
When does the derivative of a function exist at a given point?
Let f be a function and a be the given point you are considering. Then,f(x) - f(a)---------------(x-a)is the difference quotient. If the limit as x approaches a exists, then the function is differentiable at a, or we say the derivative exists at a. If that limit does not exist, then the derivative does not exist at that point.
How many lines can end in the same point?
I assume you mean that the line goes through a certain point. There is no limit to how many lines you can have through the same point.
What are the different rules of finding the limit of function?
Given a function sequence f1(x), f2(x), f3(x)..., the limit can be defined in several ways: - Point by point limit; that is, it converges to a new function at each point. - Lp convergence; that is, it converges to a new function in Lp-norm. - Almost everywhere convergent; that is, it converges to a new function except a set with measure zero.
What is a giant cluster?
There isn't really a generic term for a giant cluster - as all clusters are giant. See related question for the two types of cluster

A star cluster. See related question
What name is given to a cluster of genes with related functions along with their control sequences in bacteria?
An inducer is a cluster of genes that codes for proteins with related functions. They do this by disabling repressors, which causes the gene to be expressed.
What is the limit at a point?
let A be any subset of a metric space X a point x belongs to X is called a limit point of A if every neighbourhood of x contain a point of A other than x
