ABSTRACT
However, the use of this formula is complicated by the fact that the integral expressing t is improper, since for x = 0 the denominator of the integrand vanishes, which considerably complicates computations when the function f (x ) is given numerically or graphically. The primitive approach to surmount this difficulty, for example, the replacement of the function l / V F (x) by one which is linear near zero leads to capital errors.
