PARTICULARLY APPLICABLE TO SOME GEODETICAL PROBLEMS. 123 



We have now x, and its logarithm ; from which y and x are found 

 as follows : 



3-9065834 39065834 



a 



^ 1-2734544 12734544 



^ 0-8662328 ^ 07083380 



y- 11124-25 4-0462706 8=773349 3-8883758. 



22. The computation by subsidiary angles from the formula for 

 Case 2, Art. 19, may be as follows: 



b' 



J 0-8662328 



& 



- 0-7083380 



tan (0 = 55° . ir.35 75) 101578948 



sin (2^ = 110° . 23'.11"- 5) 99719082 

 ^os " 9-9915445 



2)19-9634527 



tan (e = 43° . 47'.42"- 2) 9-9817263 



cos e 9-8584297 



^1" ^ 9-9143866 



^' 5-0000000 



b 



i' 9-1337672 



X = 8064-61 3-9065835. 



This way of proceeding seems to have no advantage over the direct 

 process farther than being a verification.
