Mar 7, 2021 · べき関数 y = x n y=x^n y = x n の微分公式の証明に，より難しい関数 y = log x y=\log x y = lo g x の微分公式を用いるので，私はあまり好きではありません。ただ，この方法を使えばより一般の場合（冒頭の公式2）も証明できます。
Mar 7, 2021 · 公式の左辺を a a a の多項式とみる： P (a) = a n − b n P(a)=a^n-b^n P (a) = a n − b n P (b) = 0 P(b)=0 P (b) = 0 より， P (a) P(a) P (a) は (a − b) (a-b) (a − b) を因数として持つ。 そこで， (a − b) (a-b) (a − b) で割り算を行うと上の公式を得る。
Oct 13, 2022 · Let X and Y be two independent discrete random variables with PMFs $$\begin{equation} P_X(k)=P_Y(k)= \begin{cases}\frac{1}{5}, & \text{for}\ x= 1,2,3,4,5 \\\ 0 ...
