Inverse ratio of the cosine of an angle.
Notation
The secant of x is noted as: “sec(x)” which is read as “secant of x.”
Examples
- sec(60) = 2
- sec(30) ≈ 1.155
Educational note
The argument of the secant is a number and not an angle.
Therefore, it’s a linguistic shortcut to say “secant of an angle” instead of “secant of the measure of an angle.”
