**tangent**sight cross-wires for fine reverse laying. - Fermat and Descartes agreed in regarding the
**tangent**to a curve as a secant of that curve with the two points of intersection coinciding, while Roberval regarded it as the direction of the composite movement by which the curve can be described. - They consist of a long rectangular building, with a proscenium or column front which almost forms a
**tangent**to the circle of the orchestra; at the middle and at either end of this proscenium are doors leading into the orchestra, those at the end set in projecting wings; the top of the proscenium is approached by a ramp, of which the lower part is still preserved, running parallel to the parodi, but sloping up as they slope down. - The curve thus constructed should be a straight line inclined to the horizontal axis at an angle 0, the

**tangent**of the angle of elevation. - Could be done by noting the amount of deflection for each range and applying it by means of a sliding leaf carrying the notch, and it is so done in howitzers; in most guns, however, it is found more convenient and sufficiently accurate to apply it automatically by inclining the socket through which the
**tangent**scale rises. - Other improvements were: the gun was sighted on each side,
**tangent**scales dropping into sockets in a sighting ring on the breech, thus enabling a long scale for all ranges to be used, and the foresights screwing into holes or dropping into sockets in the trunnions, thus obviating the fouling of the line of sight, and the damage to FIG. - Since the early days of rifled guns
**tangent**sights have been improved in details, but the principles remain the same. - The disadvantages that still remain are that the sight has to be removed every time the gun is fired, and the amount of deflection is limited and has to be put on the reverse way to that on a
