 note = {This paper once again introduces one traditional Japanese mathematical book, Kenki Sanpo (1683) by Katahiro Takebe (1664 - 1739). In this book Takebe solved a problem of area of segment utilizing the approximate formula for the length of arc reduced as a result of polynomial interpolation. The author poses the hypothesis to reconstruct Takebe’s formula, which the formula has close resemblance to the minimax approximation polynomial.},
