WebGiven: sin(x) = 1/2. Using the trigonometric identity. sin 2 (x) + cos 2 (x) = 1. Substituting the value (1/2) 2 + cos 2 (x) = 1. cos 2 (x) = 3/4. cos(x) = ±√3/2. We know that. tan(x) = sin(x)/cos(x) Substituting the values. tan(x) =±(1/2)/( √3/2) So we get, tan(x) = ±1/√3. Therefore, cos(x) is ±√3/2 and tan(x) is ±1/√3.
