  • 2026年 6月 CPU天梯图（更新250 270K Plus 9850X3D）
    CPU天梯图更注重综合性能，只具有参考意义，选择CPU要根据需求选择。 生产力用户更偏重多核性能，可以参考综合性能天梯图 游戏用户更偏重单核性能，综合性能天梯图参考意义不大 桌面端CPU游戏性能排名：
  • arithmetic - Formal proof for $ (-1) \times (-1) = 1$ - Mathematics . . .
    Is there a formal proof for $(-1) \\times (-1) = 1$? It's a fundamental formula not only in arithmetic but also in the whole of math Is there a proof for it or is it just assumed?
  • Why is $1 i$ equal to $-i$? - Mathematics Stack Exchange
    There are multiple ways of writing out a given complex number, or a number in general Usually we reduce things to the "simplest" terms for display -- saying $0$ is a lot cleaner than saying $1-1$ for example The complex numbers are a field This means that every non-$0$ element has a multiplicative inverse, and that inverse is unique While $1 i = i^ {-1}$ is true (pretty much by definition
  • 1-1+1-1+1-1+1. . . 这个无穷数列的值是什么？如何证明？ - 知乎

  • Given a 95% confidence interval why are we using 1. 96 and not 1. 64?
    Another way to explain this would be that a z-score of +1 96 simply means that the confidence level falls within the -1 96 and +1 96 range, but on the positive side
  • Binomial expansion of $ (1-x)^n$ - Mathematics Stack Exchange
    I'm not sure how appropriate it is to answer questions this old, but compared to the methods above, I feel the easiest way to see the answer to this question is to take a = -x And substitute that into the binomial expansion: (1+a)^n This yields exactly the ordinary expansion Then, by substituting -x for a, we see that the solution is simply the ordinary binomial expansion with alternating

  • Why does an argument similiar to 0. 999. . . =1 show 999. . . =-1?
    If you can imagine a two's complement representation with infinitely many bits, you won't be surprised that in that representation the number with all bits $1$ represents $-1$ Analogously, in an infinite ten's complement representation, the number with all digits $9$ represents $-1$
  • 1 1+1 2+1 3+1 4+……+1 n=？怎么个解法？ - 知乎
    红线是n-1到n的割线，绿线是n处的切线 图像上显然，割线的斜率大于切线的斜率。 所以我们有割线的斜率 \dfrac {\ln \left ( n\right) -\ln \left ( n-1\right) } {n-\left ( n-1\right) } 大于切线的斜率 \left ( \ln n\right) '=\dfrac {1} {n} 。 我们有 \ln n-\ln \left ( n-1\right) >\dfrac {1} {n} 我们累加 \sum \left ( \ln n-\ln \left ( n-1\right
