Leibniz

Leibniz 高数级数的Leibniz判别法是什么? 怎样用Leibniz 定理算圆周率?Leibniz 定理是1/2-1/5+1/7-1/9。等于圆周率/4 既不是正项级数也不是leibniz级数的级数如何判断其敛散性? 既不是正项级数也不是leibniz级数的级数如何判断其敛散性?如：(-1)^(n+1)*(2^(既不是正项级数也不是leibniz级数的级数如何判断其敛散性?如：(-1)^(n+1)*(2^(n^2))/n! 有什么充分理由说牛顿创造了微积分?又有什么驳斥leibniz创造了微积分这个观点? 英语翻译If the modern scientific world looks back into the mirror of its coming into being,its gaze meets Leibniz – the mathematician,natural scientist,engineer,logician,philosopher,jurist,science organizer and perhaps the last universalist,who 英语翻译Leibniz then entered service in the court of the prince elector,the archbishop of Mainz,Johann Philipp von Schonborn,where he was concerned with questions of law and politics.之后，莱布尼兹为王子选择人：美因茨大教主约 设f(x)=g(x)(x-a)^n,g(x)在x=a处有n-1阶连续导数,求在x=a处的n阶f（x）用Leibniz公式,然后为什么求和里面k=0这一项是非0,不是全部都是0吗?
