through the points ,

So the first few values of , , , ..., are 2, 1, 1/2, , 1/8, , ... (OEIS A118210
and A118211).

Now consider the partial sums of these coefficients, namely 2, 3, 7/2, 10/3, 83/24, 203/60, 2459/720, ... (OEIS A118203 and A118204). As first noted by F. Magata in
1998, the sum appears to converge to the value 3.407069... (OEIS A092894),
now known as Magata's constant.
