The term tan(2θ) refers to the tangent of twice an angle, which is an important concept in trigonometry related to double-angle identities. This identity can be expressed in terms of the tangent of the original angle, allowing for simplifications in calculations involving angles that are multiplied by two. Understanding tan(2θ) helps in solving equations and analyzing functions that involve angle transformations.
