微積分老師突然要求我們上台用英文講解微分題目 這讓我很焦慮因為平常老師上課都是聽懂就好也沒有特別聽她的英文 上YouTube找的影片檔又念得有點快 ex:http://patrickjmt.com/derivatives-the-quotient-rule-a-few-basic-examples/ 可以請各位幫忙我把他說的打出來嗎? 麻煩大家了 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.138.226.102

要是只是要算式的讀法是很快 不過他還加入了很多解說

the derivative of f of x over g of x equols to:
