From tliese expressions we get tlie followiiig values of these 

 coefficients for the different points.

The values of q^ and q.^ are for the three points Xj, Xj 

 and ^3 to be taken from the three equations (10*). 

 If we put

then the roots of (13) corresponding to the points X, , X, and 

 ig are given through the formula: 



(15) r- = - (1 + ,u -/) ± V9/^ - 4(1 + ^0/ • 



One of these roots is positive, the other negative. That is 

 what I liave found through numerical calculation for different 

 values of f.i, an algebraic demonstration of this fact seeming 

 to be somewhat complicated. 



The result of this calculation is the following.
