| Jan 9 at 12:47 | comment | added | Iosif Pinelis | I agree that this is rigorous, and I did think about this possibility. However, the realization of this approach seems rather laborious, especially the gluing should be done rather carefully, and the eventual product will probably be a piecewise-defined function with complicated expressions, especially after the gluing. My efforts were directed to finding a very simple expression for a function in question. Of course, I am being apologetic here. :-) | |
