26 Ιουλ 2023 · The square of the secant function identity is a trigonometric relationship that concerns the square of the secant function, denoted as sec^2(x). It is derived from the Pythagorean trigonometric identity, which states that sin^2(x) + cos^2(x) = 1.
Formula. sec 2 θ = 1 + tan 2 θ. The square of secant function equals to the addition of one and square of tan function is called the secant squared formula. It is also called as the square of secant function identity.
In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles.
