Definition: Events in the environment that affect the behavior of an individual. Example in everyday context: You are normally very talkative during work gatherings. When your boss is present, you are less talkative during work gatherings. Your boss serves as a stimulus that changes your behavior.

2021年3月27日 · If $A$ and $B$ are $2\times 2$ matrices such that $A^2+B^2=AB$, prove that $(AB-BA)^2=O$.

2020年12月21日 · 要构造一个等式来推出结论，该等式必定是关于 I,A,B,A^2,AB,BA,B^2,...\tag {5} 的线性组合，然后根据 AB+A-B^2=0 ，去寻找能否有 AB=BA 。 我们把关于 A,B 按上述方式张成的全体记为 \mathbb {F} [A,B] ，其中 \mathbb {F} 为矩阵所在的域。 我们接下来一步一步地去研究它的结构。 首先单位矩阵应该位列其中，所以目前我们有 <I>\subset \mathbb {F} [A,B] 。 接着 <I,A,B>\subset\mathbb {F} [A,B] 也很显然。

2021年4月4日 · One commonly used formula is $a^2-b^2= (a+b) (a-b) $. It is easy to prove it from RHS to LHS algebraically, but how to prove it geometrically?

2024年5月1日 · Let $A$ and $B$ be symmetric, positive, invertible matrices. My end goal is to show that $\|A^2B\| = \|ABA\|$ in operator norm. I initially thought it could be proved as follows. By definition of similar matrices, $ABA$ is similar to $J^{-1}ABAJ$ for any invertible matrix $J$.

2014年2月24日 · =a^2-ab-ba+b^2 这两个公式的结构特征： 1、左边是两个相同的 二项式 相乘，右边是 三项式 ，是左边二项式中两项的平方和，加上或减去这两项乘积的2倍；

2009年2月4日 · （a-b）的2次方公式为（a-b）²=a²-2ab+b²，两数和（或差）的平方，等于它们的平方和，加上（或减去）它们的积的2倍即完全平方公式。 （a+b）²=a²+2ab+b²与（a-b）²=a²-2ab+b²都叫做完全平方公式。
