In geometry, a double wedge is the (closure of) the symmetric difference of two half-spaces whose boundaries are not parallel to each other. For instance, in the Cartesian plane, the union of the positive and negative quadrants forms a double wedge, and more generally in two dimensions a double wedge consists of the set of points within two vertical angles defined by a pair of lines. In projective geometry double wedges are the projective duals of line segments. (Wikipedia).

Pre-Calculus - Find All of the Solutions of an Equation Using the Double Angle Formulas
👉 Learn how to use the double angle identities to solve trigonometric equations. When we have equations with a double angle we will apply the identities to create an equation that can help solve by inverse operations or factoring. We explore the double angles for sine, cosine and tangent
