[From the Cambridge and Dublin Mathematical Journal, vol. III. (1848), pp. 120, 121.]
Suppose
— &Qs 4" &iQs—i 4"
(1).
where, as usual, Q 0 , Q 1} &c. are the coefficients of the successive powers of p in
(1 — 2pp + p 2 ) -i . Assume
where A refers to C; then expanding this expression, first in powers of g, and then
in a series of terms of the form a/(14-A 2 ).Q, and comparing these with the preceding
values of S,
o-s-r = \/(l 4- A 2 ) .A r .C
A = I (1 - V(1 - 8% V( 1 + A y = ¡1 - vU - 8*))»
