We know, using radian to degree conversion, θ in degrees = θ in radians × (180°/ pi) ⇒ 2pi/3 radians = 2pi/3 × (180°/pi) = 120° or 120 degrees ∴ sin 2pi/3 = sin 2π/3 = sin (120°) = √3/2 or 0.8660254. . .

Webb2. Now you can see that you are multiplying cos (phi) by itself and sin (phi) by itself. So, cos (phi) * cos (phi) - sin (phi) * sin (phi) = cos^2 (phi) - sin^2 (phi) What's interesting about this trig identity is that you can use it to calculate cos (phi) in terms of cos or sin, by applying the Pythagorean identity. Webb23 sep. 2024 · Enforcing the substitution $2\phi \to \phi$ and exploiting the $2\pi$-periodicity of the integrand reveals that $$\begin{align} \int_0^{2\pi}\frac{1}{1-\rho\sin(2\phi ...
Webb1. First we apply the sum formula, cos(a+b) = cos(a) * cos(b) - sin(a) * sin(b): cos(2*phi) = cos(phi + phi) = cos(phi) * cos(phi) - sin(phi) * sin(phi) 2. Now you can see that you are …
