In mathematics, trigonometric substitution is the substitution of trigonometric functions for other expressions. In calculus, trigonometric substitution is a technique for evaluating integrals.


In integral of tan^2(x)sin(x) appears to be an integration by parts problem, but this approach leads to a dead end. Instead this is a simple integral to perf

+ C (n ̸= −1). ∫. 1 x dx = ln |x| + C. ∫ tan x dx = − ln | cos x| + C. ∫ dx cos2 x. = ∫. (1 + tan2 x) dx = tan x + C. (b) Solve the following initial value problem.

a > 0 {\displaystyle a>0} These identities can be used to derive the product-to-sum identities. By setting θ=2x{\displaystyle \theta =2x}and t=tan⁡x,{\displaystyle t=\tan x,}this allows expressing all trigonometric functions of θ{\displaystyle \theta }as a rational fractionof t=tan⁡θ2{\textstyle t=\tan {\frac {\theta }{2}}}: sin⁡θ=2t1+t2,cos⁡θ=1−t21+t2,tan⁡θ=2t1−t2.

NCERT Solutions For Class 12 Physics; So, I figured out that $$\int\tan^2xdx =\int(\sec^2x-1)dx=\tan x-x+C$$ I'm trying to adapt this so I can also evaluate $\int\tan^4x$.

I need the indefinite integral of sec^6 x dx aka integral[ ( sec(x) )^6 dx]. I tried breaking it into sec^4 and sec^2 and setting sec^4 equal to (1-tan^2)^2 which I simplified down and used u substion where u = tanx du = sec^2 x dx and it got down to integral of (u^4 -2u^2 +1) du but according to Wolfram online when I do this easy integration I'm getting the wrong answer and I don't really

In (tan^2)x your 1st mistake is not writing dx. Note that dx is NOT always du!!!!! If you let u=tanx in integral (tan^2)x you get integral u^2 dx which is not (u^3)/3 + c since du= sec^2x dx BITSAT 2007: ( 1+ tan2 x / 1 - tan2 x) dx is equal to (A) log ( 1- tan x/ 1 + tan x) + c (B) log ( 1+ tan x/ 1 - tan x) + c (C) I need the indefinite integral of sec^6 x dx aka integral[ ( sec(x) )^6 dx].
