Sec Trig Identity | Square of Secant Function IdentityThe secant trigonometric identity is a fundamental relationship in trigonometry that involves the secant function, denoted as sec (x). The secant function is the reciprocal of the cosine function, which means sec (x) = 1/cos (x). This identity is derived from the Pythagorean trigonometric identity, which states that sin^2 (x) + cos^2 ...
