46 A NEW METHOD OF DETERMINING 
The equation

gives 
ee = ons (1+ y~) dy. (28) 
Hence

When p is a whole number 
+ny—1 
ie or, ay = 0; 
J oony=1 
except when » =1, when this integral is 27./—1. 
Hence it follows that 
When 7 = 0, we have 
Using the expression

we have 
((0, 0, c)) =(OF0K0) eae 2n/ (0, 1, ¢) 
for the constant term, the double value of this term being employed.
