Answer ∫ tan 1 x dx = x tan 1 x ½ ln (1x 2 ) C We will use the inetgration by parts formula to find the value of int tan 1 x dx So, now we need to integrate tan 1 x We will use the formula ∫uv dx = u ∫vdx ∫ du/dx ∫vdx dxHair In this problem, we have to evaluate the integral one minus stain Geant square X divide by second square extort BX Now we know they're detainee in squid X is Seacon square X minus one So the integral will become one minus seeking square X minus one Divide by second square X Now this negative on negative saying welcome place on one end one will become too so we can write We have ∫tan2(2x)dx Recall that, through the Pythagorean identity, tan2(x) = sec2(x) − 1 = ∫(sec2(2x) − 1)dx Split up the integral = ∫sec2(2x)dx −∫dx = ∫sec2(2x)dx −x Now, let u = tan(2x) This means that du = 2sec2(2x)dx

Best answer To find \(\int\cfrac{dx}{(1cos^2x)}\) Formula Used 2 sec2x = 1 tan2x Dividing the given equation by cos 2x in the numerator and denominator gives us, \(\int\cfrac{sec^2xdx}{1sec^2x}\)(1) Let y = tan x dy = sec2 x dx (2)Can't be applied here because the powers of secant and tangent are odd and even, respectively In light of this observation, we can evaluate the integral using one of two methods Method 1 \textbf {Method 1} Method 1 Manipulating the integrand Using the identity tan 2 ( x) = sec 2 ( x) − 1 \tan^2 (x)=\sec^2 (x)1 tan 2 ( x) = sec Prove that ∫tan^–1 (1/(1 – x x^2)) dx for x ∈ 0,1 = 2 ∫tan^–1 x dx for x ∈ 0,1 Hence or otherwise, evaluate asked in Integrals calculus by Abhilasha01 ( 376k points)
