  • Secant Formula - What is Secant Formula?, Examples - Cuemath
    When the length of the hypotenuse is divided by the length of the adjacent side, it gives the secant of the angle, of the right-angled triangle Secant is denoted as 'sec'
  • Secant function (sec) - Trigonometry - Math Open Reference
    In a right triangle, the secant of an angle is the length of the hypotenuse divided by the length of the adjacent side In a formula, it is abbreviated to just 'sec'
  • Trigonometric Identities - Math is Fun
    You might like to read about Trigonometry first! The Trigonometric Identities are equations that are true for right triangles
  • Secant and Cosecant - Algebrica
    The secant and cosecant of an angle θ are defined as the reciprocals of cos (θ) and sin (θ), extending trigonometric relationships
  • Secant Defined: What Is It Over What in Trigonometry?
    🚀 TL;DR – Key Takeaway The **secant** in trigonometry is the **reciprocal of cosine**—meaning it’s calculated as **hypotenuse divided by the adjacent side** (or **1 cosine**) It’s one of the six primary trigonometric ratios, alongside sine, cosine, tangent, cosecant, and cotangent Think of it as the “opposite” of cosine: where cosine tells you how much of the hypotenuse aligns
