The two equations are
ciwt 5 + 5e(w — 100 ae) r + wf= 0, r (w - 20 ae) + 20 a/= 0,
or, if for greater convenience we write 20 ae = 0, then
aiVT 5 + 5e (w - 0) r + wf= 0, r (w - 6) + 20 af = 0,
we have

which should be identical with the before mentioned equation in w, that is with

which completes the proof. The proof for the general form (a, b, c, d, e, f\x, y) G is
similar in principle, viz. treating for the moment <£ 2 or w as a constant, we have
in t a quintic equation and a cubic equation, in each of which the coefficients con
tain w linearly; and the elimination of r leads to the required sextic equation in w,
but there would probably be considerable difficulty in effecting the calculations.
It thus appears that assuming the solution of the central resolvent equation
for t, = ^, we also know </> : I recall that for the quintic equation whose roots are
