想用Line 整男友,讓他以為被我封鎖了,結果他竟然這樣回我 XDD
Deriving the Derivative of Inverse Tangent or y = arctan (x) - YouTube 這個方法也太有趣了XD 小編生一個小氣然後來整男友~(筆記 ------------------- dcard原文 上次看到用賴整朋友的文章讓我突然想來整整平常愛捉弄我的閃直接附圖 立馬打電話來求證 但我裝傻 所以他截圖給我看Deriving the Derivative of Inverse Tangent or y = arctan (x). In this video, I show how to derive the derivative formula for y = arctan(x). This is a super useful procedure to remember as this is how many of the inverse derivative formulas are derived! Al...
