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. Webbsin (θ) = 2/4, and csc (θ) = 4/2 Because of all that we can say: sin (θ) = 1/csc (θ) cos (θ) = 1/sec (θ) tan (θ) = 1/cot (θ) And the other way around: csc (θ) = 1/sin (θ) sec (θ) = 1/cos (θ) cot (θ) = 1/tan (θ) And we also have: cot (θ) = cos (θ)/sin (θ) Pythagoras Theorem For the next trigonometric identities we start with Pythagoras' Theorem:
