# Asymptotes Sentence Examples

If the

**asymptotes**be perpendicular, or, in other words, the principal axes be equal, the curve is called the rectangular hyperbola.We may observe that the

**asymptotes**intersect this circle in the same points as the directrices.If the tangent at P meets the

**asymptotes**in R, R', then CR.CR' = CS 2.The isothermals are approximately equilateral hyperbolas (pv= constant), with the axes of p and v for

**asymptotes**, for a gas or unsaturated vapour, but coincide with the isopiestics for a saturated vapour in presence of its liquid.The orbit has therefore two

**asymptotes**, inclined at an angle lr/m.AdvertisementHis discussion of curves of the third order turned mainly on the nature of their

**asymptotes**, and depended on the fact that the equation to every such curve can be put into the form pqr-hus = o.The work falls into two parts, which treat of the

**asymptotes**and singularities of algebraical curves respectively; and extensive use is made of the method of counting constants which plays so large a part in modern geometrical researches.It will readily be understood how the like considerations apply to other cases, - for instance, if the line is a tangent at an inflection, passes through a crunode, or touches one of the branches of a crunode, &c.; thus, if the line S2 passes through a crunode we have pairs of hyperbolic legs belonging to two parallel

**asymptotes**.The two legs of a hyperbolic branch may belong to different

**asymptotes**, and in this case we have the forms which Newton calls inscribed, circumscribed, ambigene, &c.; or they may belong to the same asymptote, and in this case we have the serpentine form, where the branch cuts the asymptote, so as to touch it at its two extremities on opposite sides, or the conchoidal form, where it touches the asymptote on the same side.As regards the so-called hyperbolisms, observe that (besides the single asymptote) we have in the case of those of the hyperbola two parallel

**asymptotes**; in the case of those of the ellipse the two parallel**asymptotes**become imaginary, that is, they disappear; and in the case of those of the parabola they become coincident, that is, there is here an ordinary asymptote, and a special asymptote answering to a cusp at infinity.AdvertisementThere are in some cases points termed centres, or singular or multiple foci (the nomenclature is unsettled), which are the intersections of improper tangents from the two circular points respectively; thus, in the circular cubic, the tangents to the curve at the two circular points respectively (or two imaginary

**asymptotes**of the curve) meet in a centre.The first book deals with the generation of the three conics; the second with the

**asymptotes**, axes and diameters; the third with various metrical relations between transversals, chords, tangents,**asymptotes**, &c.; the fourth with the theory of the pole and polar, including the harmonic division of a straight line, and with systems of two conics, which he shows to intersect in not more than four points; he also investigates conics having single and double contact.If a rectangle be constructed about AA' and BB', the diagonals of this figure are the "

**asymptotes**" of the curve; they are the tangents from the centre, and hence touch the curve at infinity.The equations to the

**asymptotes**are = t y/b and x = =y respectively.Referred to the

**asymptotes**as axes the general equation becomes xy 2 obviously the axes are oblique in the general hyperbola and rectangular in the rectangular hyperbola.Advertisement
