Bernoulli polynomial


The Bernoulli polynomialsMathworldPlanetmathPlanetmath are the sequenceMathworldPlanetmath {br(x)}r=0 of polynomialsPlanetmathPlanetmath defined on [0,1] by the conditions:

b0(x)=1,
br(x)=rbr-1(x),r1,
01br(x)𝑑x=0,r1

These assumptionsPlanetmathPlanetmath imply the identity

r=0br(x)yrr!=yexyey-1

allowing us to calculate the br. We have

b0(x)=1
b1(x)=x-12
b2(x)=x2-x+16
b3(x)=x3-32x2+12x
b4(x)=x4-2x3+x2-130
