Derivatives of sin x, cos x, tan x, e^x and ln x | Derivatives of common functions | Khan Academy這是我們老師說的,在我們新生入學時說過:各位同學,很開心你們能進XX高職,老師在那之前跟你們說一件事,很重要(凝重眼神)(同學也被嚇到了,認真聽)我之前帶過一個美容科的學姐她因為要搭校車,可是那天剛好有點延誤下課時間於是她很趕,結果一上校車就先站著,結果......公車那一天突然緊急煞車,結果...Lets say I have an equation sin x = 1/2. Then clearly, x = 30 degrees or pi/6 radians. Now if I differentiate both sides of the equation with respect to x (because both are equal, their derivatives should also be equal), I will have cos x = 0, right? But ...
