门捷列夫不等式
门捷列夫除了创立元素周期表外，还发现了一个有趣的数学定理。他从插值问题出发，推导出关于多项式及其导数的定理，这一成果后来被Boas等学者引用和推广。

The article discusses linear algebra concepts applied to polynomials, specifically the set P_n(ℝ) of real polynomials with degree ≤ n. It explores how these polynomials can be expressed using n+1 scalar coefficients and examines their properties as a vector space.
Lagrange interpolating polynomials provide a method to find a polynomial that perfectly fits a given set of distinct data points. The approach constructs a polynomial of degree at most n that passes through n+1 specified points. This technique is widely used in numerical analysis and approximation theory.
