Here's your answer. tanA + tan2A = √3 (1 – tanAtan2A), (tanA + tan2A) / (1 – tanAtan2A) = √3, tan(A + 2A) = tan π/3 Oct 24, 2023 ... The reason why is that it (almost always) maps two angles "a, b ∈ (-π/2; π/2)" to the same value "tan(2θ)", eg a = -π/3, b = π/6 with tan If 3 cot A = 4, check whether (1 - tan2 A) / (1 + tan2 A) = cos2 A - sin2 A or not. We know that the cot function is the reciprocal of the tan function. Jun 20, 2019 ... Cos2A+tan2A-1/sin2A=tan2A. ... sin ⁡ θ cos ⁡ θ , cot ⁡ θ = cos ⁡ θ sin ⁡ θ , sec ⁡ θ = 1 cos ⁡ θ , csc ⁡ θ = 1 sin ⁡ θ . Some useful trigonometric identities: sin2A+cos2A=1,tan2A+ ... Dec 25, 2023 ... If 3 cot A = 4 therefore cot A = 4/3 tan A = 3/4 to prove (1 – tan 2 A)/(1 + tan 2 A) = cos 2 A – sin 2 A Take LHS (1 – tan 2 A)/(1 + tan 2A = (2 tan A) / (1 - tan2A).
