Edits to Binomial coefficient
[edit]Welcome to Wikipedia. I see you have edited Binomial coefficient, adding the following material
The Binomial Theorem also is apparent in a ρ^th sum of a series (usually beginning with (1)).
- (1)
When continued on until the set limit (ρ) the summation expression alters with a set range of factorial relationships: specifically, the factorial of the stated variable by which summation is measured (in the above case: x) added to the limit (ρ) with one subtracted (as to allow for the fact that the first summation must include the original series with no α value in the component) divided by as to permit the value from x to be produced from the first series relationship (2).
- (2)
Thus we can gain the expression for a ρ^th summation which as is clearly visible yields the division of two factorials implicating the usage of the Binomial Expansion (3) for this ρ^th degree summation polynomial deriving from the base form (1), note that the symmetry of the Binomial Coefficient indicates that the coefficient of ρ and x-1 will be identical:
- (3)
Substituting ρ=1 yields (4):
- (4)
I presume you added this in good faith, but it is unclear what this is about (for instance what ρ is or which series is meant), or why it should be in the section where it appears. In fact I cannot make any sense out of it, nor I suppose can the average reader; I will therefore remove it. If you wish to add this to the article, please make your intentions more clear.

Ok, thank you for amending the expression graphics anyhow - I may clarify this with an extension paragraph at some point.
