Tan 1/2 theta
Web1 Jun 2024 · tan(2θ) = 2 tan θ 1 − tan2θ In this formula, we need the tangent, which we were given as tan θ = − 3 4 . Substitute this value into the equation, and simplify. tan(2θ) = 2( − 3 4) 1 − ( − 3 4)2 = − 3 2 1 − 9 16 = − 3 2(16 7) = − 24 7 Exercise 9.3.1 Given sin α = 5 8 ,with θ in quadrant I, find cos(2α) .
