WebThe cos of 26 degrees equals the x-coordinate (0.8988) of the point of intersection (0.8988, 0.4384) of unit circle and r. Hence the value of cos 26° = x = 0.8988 (approx) Cos 26° in Terms of Trigonometric Functions Using trigonometry formulas, we can represent the cos 26 degrees as: ± √ (1-sin² (26°)) ± 1/√ (1 + tan² (26°)) boys wearing earrings
