Deriving Expression for Differentiation and Summation in Special Case

Click For Summary
SUMMARY

The discussion focuses on deriving an expression for differentiation and summation in a special case involving algebraic operations and the geometric series formula, specifically the summation formula \(\sum_{k=0}^{N-1}t^{k}=\frac{t^{N}-1}{t-1}\). The variable \(k\) is defined as \(e^{-j\pi(2n/N-1)}\). Participants emphasize the need to derive the expression with respect to \(\chi\) to proceed effectively.

PREREQUISITES

Dear Friends

So, i have this special case where i have to do a differentiation and summation.
Please check the following.

ok, what you did in the bracket were algebraic operations and the use of the formula for geometric series ##\sum_{k=0}^{N-1}t^{k}=\frac{t^{N}-1}{t-1}## where ##k=e^{-j\pi(2n/N-1)}##, now you must derive the expression respect ##\chi## ...
