I studied Schoofs Algorithm described by Washington.

On page 125 he says that we could write $y'/y$ as a function of $x$, which makes sense since earlier on the page he denotes $y'= r_{2,j}(x)y$.

But I can't find any definition of $r_{2,j}(x)$ although he referenced p.47. So what would be the definition of $r_{2,j}(x)$?

  • $\begingroup$ Your second link goes to page 112, not 125. page 125 of the book is page 138 of the pdf. I did not see the statement you're referencing on either page, so I'm not sure which is the correct one. $\endgroup$ – Maeher Sep 17 at 16:25
  • $\begingroup$ I'm sorry, the links were edited. But @kelalaka helped a lot. It is in deed listed at the errata section. The reference to page 47 seemed to be false, instead page 51 would be correct. $\endgroup$ – WonderHow20 Sep 18 at 10:53
