 It will be easily seen how difficult this must be in practice and even 

 in Galbraith the computation is wrong. Again by the next method, 

 a = 3. log 

 b = 2 C. log

Here the accuracy of the result may be carried to any extent, without 

 any additional labour, merely by increasing the number of decimals in 

 the logarithms— their difference in the result arises from the errors of 

 the last calculation. As proof of the correctness— 



cosec P = 33° 47 = 0,255261
