29 lis 2020 · To provide a correction to your own work I would remove the lim at first because I want to simplifies to the maximum the expression and at the last the computation, as follows: 1 − cos x x2 = 2sin2(x 2) x2 = 2 x2 ⋅ sin2(x 2) (x 2)2 ⋅(x 2)2 = sin2(x2) (x2)2 ⋅ 1 2. therefore.
6 lut 2024 · Answer: 1 – cos (x) is equal to 2 sin² (x/2). To derive this identity, let’s use the double-angle formula for sine: sin (2θ) = 2sin (θ)cos (θ). Now, set 2θ = x: sin (x) = 2sin (x/2)cos (x/2).
