Evaluate the half angle of cosine from a triangle

👉 Learn how to evaluate the tangent of a half-angle. When given the value of the tangent of an angle, we can evaluate the tangent of half the angle using the tangent half-angle formula. When the value of any other trigonometric function of an angle is given, we can evaluate the tangent of half the angle by first creating a corresponding triangle to determine the tangent of the required angle and then solve the half-angle using the tangent half-angle formula.
