多變函數的情況,合成的方式千變萬化,所以連鎖規則寫起來式子也都長得不一樣。

但其實只要掌握一個原則,就可以寫出來。

第六頁應該是

而不是

不會用回復,上面打錯了 =(

第六頁

應該是 這樣

而不是 這樣

好像是把 t 寫成了 s ....感謝告知!

寫代碼時偷懶,複製來複製去,結果出現一堆忘記改的... Hypnotized

關於example 3 (Page 7) 的題目敘述

所求的fs(1,1) ,由於前面敘述f(x,y)

直覺比較像是將(x,y)由(1,1)代入,再解(s,t)及所求

而下面的解則是將(s,t)由(1,1)代入

請問是我誤會題意嗎 Question

好多年前寫的了,現在想不起來原題以及當時寫的時候在想什麼了,也許當時寫久累了,快結束時寫得比較偷懶。
這個符號上來說,比較精確的寫法應當是

\bigg.\frac{\partial f}{\partial s}\bigg\vert_{(s,t)=(1,1)}
