The complement of the logarithm of a sine, tangent, or secant.
secant equals one over cosine—um-m-m-m—one point oh three five.
Every ray through S1 or S2 which is not a secant determines one of them.
That which is made by a right line, whether tangent or secant, with the circumference of a circle.
The oblongs made of any secant from the same point, and of the outter segment of the secant are equall betweene themselves.
I say they are equall in the alterne angles of the secant and touch line oey, and oeu.
On any secant of an hyperbola the segments between the curve and the asymptotes are equal.
The fraction Δy/Δx is the trigonometrical tangent of the angle which the secant PP′ makes with the axis of x.
If the curve has a tangent at P the secant PP′ approaches a limiting position (see 33 below).
There is no necessary connexion between a conical projection and any touching or secant cone.
1590s, from Latin secantem (nominative secans) "a cutting," present participle of secare "to cut" (see section (n.)). First used by Danish mathematician Thomas Fincke in "Geometria Rotundi" (1583).
