WebbTo use this formula, we need to find the values of sin θ, cos θ, sin β, and cos β. Given that cos θ = -√(3)/4 and θ is in the third or fourth quadrant (π ≤ θ ≤ 3π/2). Since cosine is negative in the third and fourth quadrants, we know that the adjacent side of the corresponding reference angle is -4 and the hypotenuse is 4/√3.
