Understanding Secant (sec)
In trigonometry, the secant (sec) of an angle is defined as the ratio of the hypotenuse to the adjacent side in a right-angled triangle, or equivalently, as the reciprocal of the cosine of the angle. Mathematically, it\'s represented as:
sec(θ) = 1/cos(θ)
The secant function is periodic with a period of 2π radians or 360 degrees. It is undefined when the cosine of the angle is zero, which occurs at angles like π/2, 3π/2, etc., or 90°, 270°, etc.
This calculator helps you quickly find the secant of any given angle, whether in degrees or radians, and provides a visual representation to aid understanding.
