56 TABLES 22 AND 23. EXPONENTIAL FUNCTIONS AND LEAST SQUARES. 



TABLE 22. Exponential Functions. 

 Value of e? and e~* and their logarithms. 



TABLE 23. - Least Squares. 

 Values of P = -^f hx tr-^* d (hx). 



This table gives the value of P, the probability of an observational error having a value posi- 

 tive or negative equal to or less than x when k is the measure of precision, P = ~C * f< hx ^ 

 d(hx). For values of the inverse function see the table on Diffusion.
