...corresponding supplement of the angle BOA, or of the arc B A. The Secant of an angle, or arc, is the straight line drawn from the centre of the circle through one...the other extremity. Thus OC is the secant of the angle BOA, or of the arc B A. The secant of an arc is equal to the secant of its supplement. The Co-secant... | |
