深入理解 y = x^2 函数 (y x 2是什么函数) - 在线计算网
2024年6月22日 · y = x^2 是数学中一个基本的二次函数，它是研究二次曲线和多项式函数的基础。 在这个函数中，x 是自变量，y 是因变量，而 x^2 表示 x 的平方。 本文将详细介绍 y = x^2 函数的性质、图像以及应用。
solution verification - Proof $x^2 - y^2 = (x-y)(x+y)$ (Spivak's ...
2020年4月3日 · I am trying to prove that $x^2 - y^2 = (x-y)(x+y)$. Spivak only defines $x$ and $y$ as numbers that obey some set of axioms, so while it seems to me that we can assume they are elements of a field, he doesn't seem to formalize this notion. Here is what I have so far. I'll start with a simple lemma that $-(yx) = -yx$.
