Are the following sequences essentially the same?
https://oeis.org/A299434 = https://oeis.org/A005447 ?
https://oeis.org/A299435 = https://oeis.org/A005446 ?
If so, then some formulas could be added to the following sequences as
A299430 / A299431 = coefficients in C(x)
A299432 / A299433 = coefficients in S(x)
These sequences describe the power series C(x) and S(x) that satisfy:
C(x)^(1/2) - S(x)^(1/2) = 1
analogous to the hyperbolic cosine, sine functions.
