Using Array Formula C(olumns) and R(ows) times in excel formula
I'm looking to expand a formula that can accommodate building scenarios over a span of 5 years (columns) and 10 cases (rows).
I can effectively handle the setup for one row and generate the outcomes across various years.
I can then drag the formula down to address the rest of the cases.
However, the cases might change dynamically, and I need an adaptable and general solution. Can anyone provide some guidance on this?
I've attached a spreadsheet where I try to explain the concept in more detail.

This is the same as HansVogelaar 's formula except that I have allowed the row and column indices, k₁ and k₂, to broadcast to build the 2D array of products.
= LET( π, PI(), k₁, SEQUENCE(rows, 1), k₂, SEQUENCE(1, cols), SIN(k₁*k₂ * π/4) )
