WebA double angle calculator can be used to find the double angle of trignometric identities. Half-Angle Formula The formulas used for half-angle in trigonometry are: Sin ( θ /2) = ± √ (1-cos θ )/2 Cos ( θ /2) = ± √ (1+cos θ )/2 Tan ( θ /2) = ± Sin ( θ) / 1 +Cos ( θ) How to find Half-Angle? To find half-angle, you need to follow simple simple steps. WebTangent function ( tan (x) ) The tangent is a trigonometric function, defined as the ratio of the length of the side opposite to the angle to the length of the adjacent side, in a right-angled triangle. It is called "tangent" since it can be represented as a line segment tangent to a circle. In the graph above, tan (α) = a/b and tan (β) = b/a.
