数学极简主义
Andrzej Odrzywolek最近在arXiv上发表文章表明，仅需函数和常数1即可获得所有初等函数。论文展示了如何从eml函数引导出加法、减法、乘法和除法运算。

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.
