The unit hyperbola is blue, its conjugate is green, and the asymptotes are red. In geometry, the unit hyperbola is the set of points (x,y) in the Cartesian plane that satisfy the implicit equation = In the study of indefinite orthogonal groups, the unit hyperbola forms the basis for an alternative radial length
The pole of a line is the inversion of its closest point to the circle C, whereas the polar of a point is the converse, namely, a line whose closest point to C is the inversion of the point. The eccentricity of the conic section obtained by reciprocation is the ratio of the distances between the two circles' centers to the radius r of ...
The eccentricity is directly related to the angle between the asymptotes. With eccentricity just over 1 the hyperbola is a sharp "v" shape. At = the asymptotes are at right angles. With > the asymptotes are more than 120° apart, and the periapsis distance is greater than the semi major axis. As eccentricity increases further the motion ...
If P 0 is taken to be the point (1, 1), P 1 the point (x 1, 1/x 1), and P 2 the point (x 2, 1/x 2), then the parallel condition requires that Q be the point (x 1 x 2, 1/x 1 1/x 2). It thus makes sense to define the hyperbolic angle from P 0 to an arbitrary point on the curve as a logarithmic function of the point's value of x .
In projective geometry and related contexts, an asymptote of a curve is a line which is tangent to the curve at a point at infinity. [ 1 ] [ 2 ] The word asymptote is derived from the Greek ἀσύμπτωτος ( asumptōtos ) which means "not falling together", from ἀ priv. + σύν "together" + πτωτ-ός "fallen". [ 3 ]
When reflected in the x-axis, a line y = mx becomes y = −mx. In this case the lines are hyperbolic orthogonal if their slopes are additive inverses. x 2 − y 2 = 1 with y = x as asymptote. For lines y = mx with −1 < m < 1, when x = 1/m, then y = 1. The point (1/m, 1) on the line is reflected across y = x to (1, 1/m).
The asymptotic directions are the same as the asymptotes of the hyperbola of the Dupin indicatrix through a hyperbolic point, or the unique asymptote through a parabolic point. [1] An asymptotic direction is a direction along which the normal curvature is zero: take the plane spanned by the direction and the surface's normal at that point. The ...
The image of the Kiepert hyperbola under the isogonal transformation is the Brocard axis of triangle which is the line joining the symmedian point and the circumcenter. Let P {\displaystyle P} be a point in the plane of a nonequilateral triangle A B C {\displaystyle ABC} and let p {\displaystyle p} be the trilinear polar of P {\displaystyle P ...
