ABSTRACT
The term xar(t) can no longer be disregarded in constructing an approximation for I(x). Approximating this term by xaR(r-a)' and repeating the analysis, we expect the approximation to I(x) to be modified by the replacement of
~ e - x u v ' v p ) - l do, that is, T( . l /p)~-~" ,
[exp( -xv+y3va)v ( 'h ) -1dv7 thatis, x - v p [ e x p ( - r + ~ r ( ' l p ) - l d r .
