**tangent**of which is 1.6. - The cartesian equation is x = ti' (c2-y'")+ 2c log [{c-?/ (c.2- y2)}/{c+?i (c2+y2)il, and the curve has the geometrical property that the length of its
**tangent**is constant. - (io) The velocity q is zero in a corner where the hyperbola a cuts the ellipse a; and round the ellipse a the velocity q reaches a maximum when the
**tangent**has turned through a right angle, and then q _ (Ch 2a-C0s 2(3). - This mass is equal to 47rabcp,u; therefore Q = A47rabcp s and b =pp, where p is the length of the perpendicular let fall from the centre of the ellipsoid on the

**tangent**of sun's diameter X focal length of lenses. - 9) by the
**tangent**screw f, acting on a small toothed wheel clamped to the rod connected with the driving pinion, there was apt to be a torsion of the rod rather than an immediate action. - This wheel is acted on by a

**tangent**sight (designed by Major-General William Millar) was introduced into the navy; this was adopted by the army in 1846. - As the
**tangent**sight was placed in the line of metal, hence directly over the cascable, very little movement could be given to it, so that a second sight was required for long ranges. - The formula for length of scale is, length = sighting radius X
**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

Draw EB parallel to DC. It is clear that under these conditions, if a
**tangent**sight AF be raised to a height F representing the elevation due to the range BC, the object C will be on the line of sight. - In the navy the conditions of an unstable platform rendered quadrant elevation of little use, and necessitated a special pattern of

at A and B, meeting at T; draw TV parallel to the axis of the parabola, meeting the arc in C and the chord in V; and M draw the**tangents****tangent**at C, meeting AT and BT in a and b. - Fermat and Descartes agreed in regarding the

**tangent**sight are that only half the movement is required to raise the sight for any particular range; the ranges on the drum are easier to read, and if necessary can be set by another man, so that the layer need not take his eye from the telescope. - The
**tangent**at any point bisects the angle between the focal distances of the point, and the normal is equally inclined to the focal distances. - The smoothest and safest running is, in fact, attained when a " transition," " easement " or " adjustment " curve is inserted between the
