標題[微積] 微分算式的英文念法
時間Tue Jan 8 23:56:48 2013
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

推 Deltak :這好像應該去打工版,而且不便宜。 01/09 00:04
→ onlystayreal:不好意思第一次PO文不太清楚,只是想知道基本的念法 01/09 00:09
→ onlystayreal:不是一定要跟影片的一模一樣 01/09 00:09
推 since2005 :要是只是要算式的讀法是很快 不過他還加入了很多解說 01/09 00:30
→ since2005 :連解說都打出來 就落落長了 01/09 00:30
→ onlystayreal:只是要算式的讀法,謝謝! 01/09 00:49
推 since2005 :the derivative of f of x over g of x equols to: 01/09 01:00
→ since2005 :the denominator alone multiplied by the numerator 01/09 01:01
→ since2005 :minus the numerator multiplied by the denominator 01/09 01:02
→ since2005 :all over the denominator term squared. 01/09 01:03
推 since2005 :there's a mnemonic rhyme that I've heard. I don't 01/09 01:06
→ since2005 :dnow if that does help. Low d high minus high d 01/09 01:07
→ since2005 :low, all over low-low. 01/09 01:07
→ since2005 :Suppose we have a function y equols to x square 01/09 01:08
→ since2005 :plus 1 over x to the fifth plus x. the derivative 01/09 01:09
→ since2005 :of y equols to the denominator, x^5 + x(不照打了) 01/09 01:10
→ since2005 :mutiplied by the derivative of the numerator,x^2+ 01/09 01:11
→ since2005 :打錯了 上面最後應該改成2x 01/09 01:13
→ since2005 :mutiplied by the derivative of the numerator,2x, 01/09 01:13
→ since2005 :minus the numerator, X^2+1, multiplied by the de- 01/09 01:14
→ since2005 :rivative of the denominator, 5x^4+1 01/09 01:14

→ onlystayreal:真是太感謝你了 01/09 01:18
推 since2005 :... 我發現我有漏打很關鍵的字耶 XD 01/09 06:19
→ since2005 :第二行numerator之前 第三行denominator之前 要加上 01/09 06:21
→ since2005 :"derivative of the" 希望你報告前會看到 XD 01/09 06:22
推 adadadadad :since大的英文真好= = 01/09 13:19
→ onlystayreal:since大我看到囉!你英文真的好好喔,謝謝你 01/09 14:13
