唔知有無人做過 New Way Mathematics and Statistics Chapter 5 Limit 同 6 Differentiation 啲 exercise
我做完個 6.5(Chain Rule)同 6.6(Differentiate e),做三十條有 3 ~ 5 條既答案係錯
佢一係就唔記得乘個 constant(例:4(x+y) = 4x + y)
Implicit Rule 又唔記得加 dy/dx
Quotient Rule 就當 Product Rule 咁「抄下面 d 上面 - 抄上面 d 下面」就變咗「抄上面 d 下面 - 抄下面 d 上面」
搞到我做嗰陣懷疑個答案係咪錯,搵完幾個同學、老師先知原來佢個答案先錯
佢都好野 咁都錯
不過而家未教 Integration,唔知點 check 數
