+Title: Bernoulli numbers+Definition: The Bernoulli numbers $B_n$ are the coefficients of the exponential generating+ functon $\frac{t}{e^t-1} = \sum_{n=0}^\infty \frac{B_nt^n}{n!}$.+Parameters: ''+Comments:+ comment-sign-convention: Some authors prefer to define $B^+_n = (-1)^n B_n$ as Bernoulli+ numbers.+Formulas:+ formula-cosh: $\sum_{n=0}^\infty \frac{B_nt^n}{n!} = \frac{t}{2}\left(\coth \frac{t}{2}-1)\right)$.+ formula-zeta: $B_n = (-1)^{n+1} n \zeta(1-n)$ for $n\geq 1$, where $\zeta$ is the+ Riemann zeta function.+Programs:+ program-sage:+ language: Sage+ code: numbers = [bernoulli(n) for n in range(1..10)]+References: {}+Links:+ Wiki:+ title: 'Wikipedia: Bernoulli number'+ url: https://en.wikipedia.org/wiki/Bernoulli_number+Similar tables: ''+Keywords: ''+Tags:+- sequence+- generating function+- special values+Data properties:+ type: Q+Numbers:+ '0': '1'+ '1': -1/2+ '2': 1/6+ '3': '0'+ '4': -1/30+ '5': '0'+ '6': 1/42+ '7': '0'+ '8': -1/30+ '9': '0'+ '10': 5/66+ '11': '0'+ '12': -691/2730+ '13': '0'+ '14': 7/6+ '15': '0'+ '16': -3617/510+ '17': '0'+ '18': 43867/798+ '19': '0'+ '20': -174611/330+ '21': '0'+ '22': 854513/138+ '23': '0'+ '24': -236364091/2730+ '25': '0'+ '26': 8553103/6+ '27': '0'+ '28': -23749461029/870+ '29': '0'+ '30': 8615841276005/14322+ '31': '0'+ '32': -7709321041217/510+ '33': '0'+ '34': 2577687858367/6+ '35': '0'+ '36': -26315271553053477373/1919190+ '37': '0'+ '38': 2929993913841559/6+ '39': '0'+ '40': -261082718496449122051/13530+ '41': '0'+ '42': 1520097643918070802691/1806+ '43': '0'+ '44': -27833269579301024235023/690+ '45': '0'+ '46': 596451111593912163277961/282+ '47': '0'+ '48': -5609403368997817686249127547/46410+ '49': '0'+ '50': 495057205241079648212477525/66+ '51': '0'+ '52': -801165718135489957347924991853/1590+ '53': '0'+ '54': 29149963634884862421418123812691/798+ '55': '0'+ '56': -2479392929313226753685415739663229/870+ '57': '0'+ '58': 84483613348880041862046775994036021/354+ '59': '0'+ '60': -1215233140483755572040304994079820246041491/56786730+ '61': '0'+ '62': 12300585434086858541953039857403386151/6+ '63': '0'+ '64': -106783830147866529886385444979142647942017/510+ '65': '0'+ '66': 1472600022126335654051619428551932342241899101/64722+ '67': '0'+ '68': -78773130858718728141909149208474606244347001/30+ '69': '0'+ '70': 1505381347333367003803076567377857208511438160235/4686+ '71': '0'+ '72': -5827954961669944110438277244641067365282488301844260429/140100870+ '73': '0'+ '74': 34152417289221168014330073731472635186688307783087/6+ '75': '0'+ '76': -24655088825935372707687196040585199904365267828865801/30+ '77': '0'+ '78': 414846365575400828295179035549542073492199375372400483487/3318+ '79': '0'+ '80': -4603784299479457646935574969019046849794257872751288919656867/230010+ '81': '0'+ '82': 1677014149185145836823154509786269900207736027570253414881613/498+ '83': '0'+ '84': -2024576195935290360231131160111731009989917391198090877281083932477/3404310+ '85': '0'+ '86': 660714619417678653573847847426261496277830686653388931761996983/6+ '87': '0'+ '88': -1311426488674017507995511424019311843345750275572028644296919890574047/61410+ '89': '0'+ '90': 1179057279021082799884123351249215083775254949669647116231545215727922535/272118+ '91': '0'+ '92': -1295585948207537527989427828538576749659341483719435143023316326829946247/1410+ '93': '0'+ '94': 1220813806579744469607301679413201203958508415202696621436215105284649447/6+ '95': '0'+ '96': -211600449597266513097597728109824233673043954389060234150638733420050668349987259/4501770+ '97': '0'+ '98': 67908260672905495624051117546403605607342195728504487509073961249992947058239/6+ '99': '0'+ '100': -94598037819122125295227433069493721872702841533066936133385696204311395415197247711/33330
