How to Integrate Sqrt(1 + x^2) and Sqrt(a^2 + x^2) 「很久很久以前,某個富饒的王國有位小國王,他的母后想給他全世界最好的東西。於是,她買了全世界最華麗的衣服給小國王,但小國王看出了藏在這些衣服中的毒物,寧願裸身以示眾人。」其實,這樣的童話離我們並不遠。才在不久之前綠色和平組織(Greenpeace)針對某些高端品牌在製造童裝時使用有毒的化學物質一事The first step in integrating sqrt(1 + x^2) is to make the trigonometric substitution x = tan(u) and dx = sec(u)^2 du. Then the integral of sqrt(x^2 + 1) becomes ∫ sqrt(x^2 + 1) dx = ∫ sqrt(tan(u)^2 + 1) * sec(u)^2 du = ∫ sqrt(sec(u)^2) * sec(u)^2 du = ∫ ...

How to Integrate Tan^2(x) and Tan^3(x), Tangent Squared and Cubed (取自Cara Delevingne Instagram) 在這世上含著金湯匙出生的豪門貴族不計其數,但可以讓我們參與成長過程卻是寥寥無幾。這位可說是史上年紀最小的時裝伸展台超模Hudson Kroenig,相信各位CHANEL狂熱迷對這位Q版模特兒一點也不陌生,沒錯年紀小小的他早已是時尚老佛爺KTo integrate the function tan^2(x), we apply the first key identity. This transforms our integral into ∫ tan^2(x) dx = ∫ [sec^2(x) - 1] dx = [ ∫ sec^2(x) dx ] - [ ∫ 1 dx ] = -x + ∫ sec^2(x) dx Since the derivative of tan(x) is sec^2(x), it implies that th...

How do I integrate tan^2(x)? - YouTube 近日受ACE HOTEL 與BEAMS 的邀約一起打造了兩款聯名包袋,分別為背包和腰包。不同於PORTER 此前與MARNI 推出的春夏系列或是商務系列,此次的聯名作品完全採用簡潔的素色呈現,並以帆布材質強調了耐用性能,藤狀的皮革也代替金屬拉鍊頭,而打開包袋後還能在細節處看到ACE HOTEL 的In this video, I demonstrate how to find the anti-derivative or the integral of tan^2(x). This would normally be quite a difficult integral to solve. However, the ever powerful trigonometric identities make this an easy problem. By realising that tan^2(x)...
