Our Secant Calculator helps you quickly find the secant of an angle (sec(x)) in both degrees and radians. Understand this fundamental trigonometric ratio, which is the reciprocal of the cosine function. Perfect for solving geometry, physics, and engineering problems with ease and accuracy using this free online tool.
Formula:
The Secant of an angle x is defined as the reciprocal of its cosine:sec(x) = 1 / cos(x)
Where x is the angle in degrees or radians, and cos(x) is the cosine of that angle. Note that sec(x) is undefined when cos(x) = 0 (e.g., at 90° or 270°).
