Once you arrived to =\int^\pi_0\sin x (2\sin^2x) dx you do the following \int_0^{\pi } 2 \sin (x) \left(1-\cos ^2(x)\right) \, dx and then substitute \cos(x)=u\rightarrow -\sin(x)\,dx=du The Once you arrived to = ∫ 0 π sin x ( 2 sin 2 x ) d x you do the following ∫ 0 π 2 sin ( x ) ( 1 − cos 2 ( x ) ) d x and then substitute cos ( x ) = u → − sin ( x ) d x = d u The Om α = 360º (helt varv), så är x = 2 π (cirkelns omkrets). Alltså är 1º = 2π/360 = π/180 = 0,01745 radianer och 1 radian = 180º/π = 57,3º Funktionerna y = sin x och y = cos x är alltså definierade för alla x, medan för y = tan x och y = cot x vissa värden måste uteslutas.

Learn more about sin plot, plot, sin Proof 2: We can prove that $$\cos^2(x) - \sin^2(x) = 1 - 2\sin^2(x)$$ 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.
