I/ a etc. _3 . . etc. 11 APPROXIMATE SUMMATION In practice, we perform the operation of integration by relying on our knowledge of the form A must have in (i) to yield the function y as its differential coefficient and our ability to do so depends thus on the possibility of differentiating a wide range of functions. The method of summation set out above is analogous. It is, however, a method of much less extensive utility, because the operation A is of much more restricted range than differentiation in the infinitesimal domain, The main reason for this is that there is no operation in the finite domain analogous to ; dx f( Exact summation of inverse operation many = fa*f( u discrete series A" 1 and we have , u) dx du is ) ......
