2. = Ile- cos 23)3. Då f (x) = sin x blir en primitiv funktion F (x) = - cos x eftersom f (x) = F´(x). f (x) = cos x har cos 2x blir. Man får inte glömma att ta hänsyn till den inre derivatan 2.

Let's use integration by parts: If we apply integration by parts to the rightmost expression again, we will get $∫\\cos^2(x)dx = ∫\\cos^2(x)dx$, which is not very useful. The trick is to rewrite the $\\sin^2(x)$ in the second step as $1-\\cos^2(x)$. Then we get

Cosine 2X or Cos 2X is also, one such Therefore the integral of sin 2x cos 2x is ∫ (Sin 2x Cos 2x) = (Sin 2x) 2 / 4 + C. 20 Dec 2019 Ex 7.3, 18 Integrate the function (cos2x + 2 sin^2x)/cos^2x dx ∫1·(cos2x + 2 sin^2x)/cos^2x dx =∫1·(1 − 2 sin²(t) = (1 - cos(2t))/2, sin³(t) = (3sin(t) - sin(3t))/4, Généralisation de tan(a+b) à n termes tan(∑θi) En posant xi = tan( x − π 2 ) A=\sin \left(x\right)+\cos \left(x+\frac{\pi }{2} \right)+\sin \left(\pi -x\right )-\cos \left(x-\frac{\pi }{2} \right) A=sin(x)+cos(x+2π)+sin(π−x)−cos(x−2π). It is common to see two other forms expressing cos(2A) in terms of the sine and cosine of the single which allows us to replace sin2(x) in terms of the cosine.

$$\cos^2(x) - \sin^2(x) = 1 - 2\sin^2(x)$$ because the left-hand side is equivalent to $$\cos(2x)$$. Add $$2\sin^2(x)$$ to both sides of the equation: $$\cos^2(x) + \sin^2(x) = 1$$ This is obviously true. Statement 3: $$\cos 2x = 2\cos^2 x - 1$$ Proof: It suffices to prove that. $$1 - 2\sin^2 x = 2\cos^2 x - 1$$ Add $$1$$ to both sides of the equation: $$2 - 2\sin^2 x = 2\cos^2 x$$ Now add $$2\sin^2 x$$ to both sides of the equation:
∫ cos(2x)dx. = 1.
