Feb 25, 2017 · An approximate identity (in the sense that you've described) is a sequence of operators, usually derived from some "nice" class, that converge to the identity operator in the sense that you …

Jun 21, 2024 · In general, if you want to approximate an ellipse with circular arcs, you need two consecutive arcs to have the same tangent at the common endpoint, to give a smooth enough curve.

239/169 is a pretty nice approximation to root 2 at 1.414201183. That is from the equation 2x^4=y^2+1 with solution x=13, y=239, yielding sqrt (2)=sqrt (y^2+1)/x^2 ~ y/x^2.
