secants
Lines piercing curves
Secants is the plural of secant.
In geometry, a secant is a line that intersects a curve at two or more points—distinguished from a tangent, which touches at only one.
In trigonometry, the secant of an angle is the reciprocal of the cosine: The secants of 0° and 180° are 1 and -1.
