122 A NEW METHOD OF DETERMINING 
Then in a similar manner from 
C=y + y.sin*Q 
logqg= log f+ y 
Yo V2 a : 3 Yoo, Ee 
L=s (4 see ) sin 2 74 s( av — js) sin4 
2 f? 
where s = 206264’.8, log”, = 9.63778, 
we find the values of Q, C, log ¢, «, and y. 
Thus we have found all the quantities entering into the expression 
9 
(-) = (C— qcos (E’ — Q)) (1—F cos ( 2 + Q)). 
Instead of this, we use the transformed expression 
a 
({) =" (1 + —2acoa(H—@Q)) * (1+ —2e08(B' + Q)*, 
and have, for finding the values of V, a, b°, the equations 
Q 
a = sin y 
? — sin val 
q 
a=tgsyz 
b= tg 5 Xa
