x = (kpi)/2 x = +- (2pi)/3 + 2kpi Use trig identity: sin a + sin b = 2sin ((a + b)/2). You can simplify with the Pythagorean identities as you desire.1. Step 1: At first, we will write 3x as 2x+x, and then we will apply sin 3 x-3 sin x =-4 sin 3 x ⇒ sin 3 x =-1 4 sin 3 x-3 sin x ⇒ 4 sin 3 x =-1 4 sin 3 x + 3 4 sin x ⇒ sin 3 x = 3 4 sin x-1 4 sin 3 x. L'Hospital's Rule states that the limit of a quotient of functions is equal to the limit of the quotient of their derivatives. Misc 2 Prove that: (sin 3𝑥 + sin 𝑥) sin 𝑥 + (cos 3𝑥 – cos 𝑥) cos 𝑥 = 0 Lets calculate (sin 3x + sin x) and (cos 3x – cos x) separately We know that sin x + sin y = sin ( (𝑥 + 𝑦)/2) cos ( (𝑥 − 𝑦)/2) Replacing x with 3x and y with x sin 3x + sin x = 2sin ( (3𝑥 + 𝑥)/2) cos ( (3𝑥 − sin ( 3x) = 2 * sin (x) * (1-sin x²) + sin (x) * (2 sin² x -1) Ce résultat est faux parce que est égal à , et pas à . Most questions answered within 4 … Since this is $\cos 3x +i\sin3x$, we can conclude that $\cos3x=\cos^3x-3\cos x\sin^2x$ and $\sin3x=3\cos^2x\sin x-\sin^3x$.
