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 Tan 2A=cot(A-15) Or, Tan 2A =Tan [90-(A-15)] Or,Tan2A=Tan(90+15-A) Or,Tan2A=Tan(105-A) This implies, 2A= Oct 18, 2022 ... 13.ii) tanθ + tan2θ + tanθ.tan2θ =1 Solve the following Trigonometric Equation Or, tanA + tan2A + tanA.tan2A = 1 NEB 12 chapter 18 ... We will be using the trigonometric ratios of complementary angles to solve the given question. tan (90° - θ) = cot θ
