645 OF ENGINEEBING FORMULÆ. Hyperbola. The transverse axis of a hyperlwla a b is that part of the axis which, if continued, would join an opposite cone. The conjugate axis is a line drawn through the centre of the transverse axis at right angles to it. The parameter is the chord of the curve drawn through the focus at right angles to the axis. . . The focus is a point in the axis where the ordinate is = J diameter. T = Transverse axis. C — Conjugate axis. x = Abscissa. y = Ordinate. Parameter
