dx, = 2 dt/(1 + t2), Det gäller däremot att 1 + tan2x = 1 + sin2x/cos2x = (cos2x + sin2x)/cos2x Kedjeregeln ger att (d/dx)(sin3x) = 3y2 cos x = 3 sin2x cos x.

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.

To evaluate the second integral we can use the identity tan2(x) + 1 = sec2(x) a second time. Doing this gives: tan2 x( )dx = sec2 x( ) 1. (. )dx = tan x( ) x + C. f (x). sin x + C, cos x. cos x + C, -sin x.

Best Answer 100% (7 ratings) Previous question Next question Get more help from Chegg. Solve it 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 $\int\tan^4x$.
