https://people.eecs.berkeley.edu/~wkahan/EndErErs.pdf page 5: (y - sqrt(y^2 + 1)) - 1/(y + sqrt(y^2 + 1)) is not zero for all y. I assume he means at (y - sqrt(y^2 + 1)) + 1/(y + sqrt(y^2 + 1))
No, he means what he wrote, which is |y-√(y²+1)| - 1/(y+√(y²+1)). In D notation: abs(y-sqrt(y^^2+1)) - 1/(y+sqrt(y^^2+1)).
