integrate sec 2 x

How to Integrate Sqrt(1 + x^2) and Sqrt(a^2 + x^2)別碰另外兩條大聖和小星在電線桿上下二頭修電路。 大聖在上頭喊道:「小星,抓住下面四條電線的兩條。」小星問:「是哪兩條?」「隨便兩條好了,」大聖說道:「你抓好了嗎?」 「抓好了。」「有沒有覺得什麼不對勁?」「沒有啊,有什麼不對勁?」 「好極了,那千萬別碰到另外兩條,那上面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 CubedThis is a true story from the Japanese Embassy in US..!!!這是一個發生在日本駐美使館真實的故事..!!!A few years ago, Prime Minister Mori was given some Basic English convTo 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 to Integrate [1/(x^2 + 1)] dx? | Physics Forums - The Fusion of Science and Community某日一位小姐去買肉圓。 小姐:老闆,我要兩個小的帶走!由於生意好,過了一會兒,老闆怕忙中有錯,在下鍋前於是問:「小姐,你那兩粒是小的嗎?」該小姐臉一紅,恨恨地回了一句:老闆,你那兩粒才是小的!OK, as you asked for it: FIRST u = x^2 + 1, du/dx = 2x, du/2x = dx [tex]\int\frac{1}{x^2+1} \ dx = \int\frac{1}{u} \ \frac{du}{2x}[/tex] I can not do further because the x variable is still exist. SECOND [tex]x = tan \ \...

Integrate e^x(1-e^2x)^(1/2)dx - Math Help Forum一對情侶在公園裡大聲爭吵,女的罵男的說:「像你這麼渾蛋的男人,只有母狗才會喜歡你。」 男的很生氣的回答道:「你居然敢這樣罵我,太過分了,我們分手。 反正我爺爺昨天剛過戶一萬張台積電的股票給我這個長孫, 我有這麼多錢,難道還會擔心找不到女朋友嗎?」 男的說完後轉身就走。結果走不到幾步後,突然背後傳來幾Hi, I was wondering if you guys could check my work for indefinite integral of (e^x)(sqrt{1-e^2x) Let u=e^x The integral becomes: integral of sqrt(1-u^2) Then I do trigonometric substitution where I let u=sinx, and I get: 1/2 sin^-1(x) + (x/2)*(1 - x^2)^1...

How do I integrate tan^2(x)? - YouTube爸: 我的好孩子你拿著牙刷在幹甚麼?子: 沒有啦!只是擦屁屁時候,便便走進了指界隙縫而已......爸: 那好像是我的牙刷耶......子: 是呀!爸: 那麼只是今天的事嗎?子: 才不是啦......最近學擦屁屁經常都會這樣,已經一個星期多了。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)...
