Editing Bernoulli polynomials (section)

===Generating functions===
The generating function for the Bernoulli polynomials is
<math display="block">\frac{t e^{xt}}{e^t-1}= \sum_{n=0}^\infty B_n(x) \frac{t^n}{n!}.</math>
The generating function for the Euler polynomials is
<math display="block">\frac{2 e^{xt}}{e^t+1}= \sum_{n=0}^\infty E_n(x) \frac{t^n}{n!}.</math>
