Proof: d/dx(e^x) = e^x | Derivatives of common functions | Khan Academy有一對夫婦,丈夫常常和豬朋狗友打保齡球,老婆不準他再去打,一天晚上,老婆發現在自己的煙抽完了,便叫丈夫去買,丈夫沒有辦法只好去買,可是已經很晚了,附近的小賣部都關門了。這可把丈夫急壞了,丈夫突然想到酒吧應該有賣煙的,於是丈夫去了,到了酒吧那個丈夫一眼就看見吧台座著一位漂亮的小姐,於是他走過前去跟那位Try looking at it this way, maybe this will answer your question. d/dx [ln(e^x)] = d/dx [ln(e^x)] I don't need to prove that, right? It's obvious, everything is equal to itself. And then he differentiates the right hand side and gets d/dx [x*lne] = dx/dx ...
