comment Calculate pairwise cosine distance only returning the lower triangular matrix
@Paul I updated the question to make it a bit more clear that I'm looking for an alternative cosine calculation that would only calculate the lower triangular matrix rather than the full symmetric matrix.

comment Calculate pairwise cosine distance only returning the lower triangular matrix
@Paul I thought about whether this was a programming or math question, but since it is more about the method of calculation than the implementation, I was thinking it was indeed more of a math question. Do you disagree?

comment Using Lagrange multipliers to find shortest distance between two straight lines
Thanks, but as @user84413 mentioned, it should be solved using Lagrange multipliers.

comment How can I show that $\begin{pmatrix} 1 & 1 \\ 0 & 1\end{pmatrix}^n = \begin{pmatrix} 1 & n \\ 0 & 1\end{pmatrix}$?
This was rather enlightning, thanks for such a late answer!
