Derivatives of sin x, cos x, tan x, e^x and ln x | Derivatives of common functions | Khan Academy妓者工作一個打扮入時的女子深夜漫步鄭州頭,一巡警問道:幹什麼的? 女子答:做妓者工作的。 巡警肅然起敬,溫和的問道:請問哪家報社的? 妓女羞答道:晚抱的。 哪家晚報? 妓女羞答道:和男晚抱。 巡警:河南晚報,不錯不錯,我喜歡! 妓Unfortunately there's no proof currently on Khan of the derivatives of sine, cosine, or tangent. Also, the derivative of tangent is secant squared. `1/cos x = sec x` `d/dx (tan x) = 1/cos^2 x = sec^2 x` As for proofs, here's a good proof of the derivative...
