Bernoulli Inequality
 | (1) |
where , . This inequality can be proven by taking a Maclaurin Seriesof ,
 | (2) |
Since the series terminates after a finite number of terms for Integral , the Bernoulli inequalityfor is obtained by truncating after the first-order term. When , slightly more finesse is needed. In thiscase, let so that , and take
 | (3) |
Since each Power of multiplies by a number and since the Absolute Value of the Coefficient ofeach subsequent term is smaller than the last, it follows that the sum of the third order and subsequent terms is a Positivenumber. Therefore,
 | (4) |
or
 | (5) |
completing the proof of the Inequality over all ranges of parameters.
