Hello Student, please find the solution: Cos A+Cos 2 A=1 => cosA = 1 – cos 2 A = sin 2 A So, Required is sin 2 A + sin 4 A = Cos A+Cos 2 A =1 I hope the solution is clear Thanks. Sep 13, 2020 · Now, substitute the value of x in 1 cos −1 1−𝑥 , we get. 2 1+𝑥 = ½ cos-1 (cos 2 θ) = ½ (2 θ) = θ = tan −1 √𝑥. Solution: We can write 1+ sin x as, And. LHS: 𝑥-1 2 cos(2) = cot ( 𝑥 ) 2 sin(2) = cot-1 (cot (x/2) = x/2 [Hint: Put x = cos 2 θ] Solution: Divide each term by √2 cos θ = RHS. Hence proved. Solution: LHS
