mr. w.h.l. russell on the theory of definite integrals.
The following are instances of the application of this method obtained by using series I., III., IV.:—
Again, we know that
from which we may deduce the following:
Now consider the series
where () is greater than . Then by the above formula
and we find for the sum of the series,
In like manner we can find the sum of the series
where is greater than , than .
