泰勒函数万能公式?
泰勒公式(Taylor’s formula)
泰勒中值定理:若函数f(x)在含有x的开区间(a,b)有直到n+1阶的导数,则当函数在此区间内时,可以展开为一个关于(x-x。)多项式和一个余项的和: f(x)=f(x。)+f'(x。)(x-x。)+f”(x。)/2!*(x-x。)^2,+f”'(x。)/3!*(x-x。)^3+……+f(n)(x。)/n!*(x-x。)^n+Rn(x)
其中Rn(x)=f(n+1)(ξ)/(n+1)!*(x-x.)^(n+1),这里ξ在x和x.之间,该余项称为拉格朗日型的余项。 (注:f(n)(x。)是f(x。)的n阶导数,不是f(n)与x。的相乘。)
多项式函数指的是什么?
多项式函数指的是一个常数项、一次项、二次项、三次项等等数次幂项组成的函数,且每个项的系数都是实数或复数。例如,$f(x)=ax^3+bx^2+cx+d$ 就是一个三次多项式函数,其中 $a$、$b$、$c$、$d$ 都是实数。
多项式函数在数学中非常重要,它们具有很多有用的性质和特征,可以用于解决各种类型的数学问题。

- 66题我想用泰勒公式来证明。显而易见的有x∈(a,b),使得f(x)>0且f(x)=0。然后将f(a)在这个点泰勒展开。问题的关键是如何用数学需要论述出存在这个点,没思路啊。总不能说显而易见存在这么个点吧?

泰勒中值定理不太懂,:有人说是拉格朗日中值定理的无限展开, 即 f(x)=f(x。)+f ’(x。
- 泰勒中值定理不太懂,:有人说是拉格朗日中值定理的无限展开,即 f(x)=f(x。)+f ’(x。)(x-x。),然后对f ’(x。)(x-x。)再展开就出现二阶导,但是我不会展。。。。
- 不会
