Let $P_{[p/q]}^{(c)}(x)$ denote the $[p/q]$ Padé approximant associated with the square-root expansion at $c$, and let $\beta_m^2(x,\sqrt{c})$ be the square biroot approximation. S…

For a positive expansion parameter $c$, let $\beta_m^2(1,c)$ denote the factored square biroot evaluated at $1$. Factored square-biroot identity. The value is … The source presents…
