Named formula for integration

M

I have a tool for integrating and differentiating functions using
Excel, see
http://www.engineersexcel.com/Tools/Function Calculus/Description.htm

I have 2 questions:

1. Can a named formula be used for integration ? That is, if a named
range, say X(n) has n numbers in it, can there be a named formula Y(n)
that works as follows:

Y(1) = X(1)

Y(n) = Y(n-1) + X(n) for all n > 1 ?

2. Is there a way a data table can be stored as a named range ?

(If the above are possible, then it will be possible to rewrite the
tool without any calculations on the spreadsheet itself.)

Any comments would be appreciated. Thank you.
