Webevaluate integral tan^3x*sec^6x dx from pi/4 to pi/2 (PLEASE check my calculation and see what is wrong with it) (sec^2x-1)sec^5x secx*tanx dx. u=secx, du=secxtanx. (u^2-1) (u^5) du=u^7-u^5 du = (1/8)u^8- (1/6)u^6= (1/8)sec^8- (1/6)sec^6 = 0 - 0 - 2 + 4/3= -2/3. however, the correct answer is 22/105*sqrt2 - 8/105. I know the answer is pobably ...

Find the Integral tan(3x) Mathway
Webx = 1 + tan 2 x = 1 + u 2. See Example 1.8.14. When m m is even and n = 0 n = 0 — that is the integrand is just an even power of tangent — we can still use the u = tanx u = tan x substitution, after using tan2x= sec2x−1 tan 2 x = sec 2 x − 1 (possibly more than once) to create a sec2x. sec 2 x. See Example 1.8.16. WebEntonces, tenemos: ∫ sin(x) cos(x) dx = (1/2)∫ sin(2x) dx = -(1/4)cos(2x) + C ∫ tan(x) dx Podemos utilizar la identidad trigonométrica sec^2(x) = 1 + tan^2(x) para transformar la integral. Entonces, tenemos: ∫ tan(x) dx = ∫ sec^2(x) - 1 dx = tan(x) - x + C Es importante tener en cuenta que las identidades trigonométricas no siempre ... infinity 読み方

WebFeb 3, 2024 · Explanation: I = ∫tan2(x)sec(x)dx Let tan2(x) = sec2(x) − 1 which comes from the Pythagorean identity: I = ∫(sec2(x) − 1)sec(x)dx = ∫sec3(x)dx − ∫sec(x)dx The integral of sec(x) is well known: I = ∫sec3(x)dx −ln( sec(x) + tan(x) ) The integral of sec3(x) can be found through integration by parts with u = sec(x) and dv = sec2(x)dx at this link. WebFind the Integral tan (3x) tan (3x) tan ( 3 x) Let u = 3x u = 3 x. Then du = 3dx d u = 3 d x, so 1 3du = dx 1 3 d u = d x. Rewrite using u u and d d u u.
