But, since the terms A, B, C, &c. are to be divided by e , e 3 , e 5 , 
See. respectively, it will be best to divide them by these quan- 
tities, before we begin the arithmetical calculations ; otherwise 
much unnecessary labour must be taken. The terms, then, 
being so divided, and the proper value of e being written for it, 
viz. V 5°, we shall have as below :
