Webcos (2x) = cos 2 (x) - sin 2 (x) cos (2β) = cos 2 (β) - sin 2 (β) cos (2β) = (-⅗) 2 - (-⅘) 2 cos (2β) = -7/25 Finally, solve for the exact value of tan (2β) using the tangent trigonometric identity tan (x) = sin (x) / cos (x). For this part, let θ = 2β and then substitute sin (2β) = 24/25 and cos (2β) = -7/25.
