log n微分

§3-4 對數函數與指數函數在激吻過後感到迷惑(點圖看大圖喔)3-4 對數函數與指數函數 (甲)對數函數的微分與積分 (1)要討論對數函數的導函數,首先觀查察f(x)=logax在x=1 處的導數。 1 1 log 1 log log 1 ( ) (1) 1 = − − − = − − x x a a x a x x f x f,故 1 1 limlog 1 ( ) (1) lim 1 1 − → → = − − x x a x x x f x f...

樣本平均數、變異數和共變異數 | 線代啟示錄 每人挑一格吧!25年前,我在高中時期,也曾經思考「自由度」為何是 n-1 ? 假如 n 很大, n 與 n-1的差別不顯著。 若 n=3,舉個例子:7, 8, 9三個數字,平均值為8, 7與8差1, 9與8也是差1, 直覺看來,標準差是1。 上例當中,7, 8, 9三個數字,使用計算標準差的公式,除以 ......
