What is conjugate diameter in hyperbola?

Conjugate diameters When two diameters of a hyperbola bisects all chords parallel to the others, then two diameters are said to be conjugate. If y=mx and y=m1x are the two conjugate diameters, then. mm1=a2b2

What is the meaning of conjugate diameters of ellipse?

. Conjugate diameter : Two diameters of an ellipse are said to be conjugate diameter if each bisects all chords parallel to the other. The coordinates of the four extremities of two conjugate diameters are. P(acos varphi ,bsin varphi ),;,{P}'(-acos varphi ,-bsin varphi )

Are conjugate diameters of an ellipse perpendicular?

Generally, conjugate diameters of an ellipse or a hyperbola are not perpendicular. However, for these conics exists exactly one pair of perpendicular conjugate diameters. Pair of perpendicular conjugate diameters of an ellipse or a hyperbola are called axes of that conic.

What is meant by conjugate lines?

1 of a conic section : two lines each of which passes through the pole of the other. 2 of a quadric : two lines so arranged that each intersects the polar line of the other.

What is conjugate points in mathematics?

In differential geometry, conjugate points or focal points are, roughly, points that can almost be joined by a 1-parameter family of geodesics. For example, on a sphere, the north-pole and south-pole are connected by any meridian. … All geodesics are locally length-minimizing, but not globally.

What do you mean by conjugate diameter?

In geometry, two diameters of a conic section are said to be conjugate if each chord parallel to one diameter is bisected by the other diameter. For example, two diameters of a circle are conjugate if and only if they are perpendicular.

What is the conjugate of hyperbola?

The hyperbola whose transverse and conjugate axes respectively are the conjugate and transverse axes of a given hyperbola is called the conjugate hyperbola of the given hyperbola. … The conjugate hyperbola of the hyperbola x 2/a 2 y 2/b 2 = 1 is x 2/a 2 y 2/b 2 = -1.

What do you mean by conjugate hyperbola?

: either of two hyperbolas having the same asymptotes, the conjugate axis of each being the transverse axis of the other.

What is confocal ellipse and hyperbola?

In geometry, two conic sections are called confocal, if they have the same foci. … In the mixture of confocal ellipses and hyperbolas, any ellipse intersects any hyperbola orthogonally (at right angles).

Is a circle a type of ellipse?

A circle is a special case of an ellipse, with the same radius for all points. By stretching a circle in the x or y direction, an ellipse is created.

How do you find the director of a circle of an ellipse?

Director circle of an Ellipse The director circle is the locus of the point of intersection of pair of perpendicular tangents to an ellipse. x2 + y2 = a2 + b2, which is the equation of the director circle.

What is the general equation of ellipse?

The standard equation for an ellipse, x 2 / a 2 + y2 / b 2 = 1, represents an ellipse centered at the origin and with axes lying along the coordinate axes. In general, an ellipse may be centered at any point, or have axes not parallel to the coordinate axes.

What is the equation of ellipsoid?

An ellipsoid is symmetrical about three mutually perpendicular axes that intersect at the centre. If a, b, and c are the principal semiaxes, the general equation of such an ellipsoid is x2/a2 + y2/b2 + z2/c2 = 1.

What is eccentric angle?

Let P be any point on the ellipse. Draw PN perpendicular to the major axis and produce it to meet the auxiliary circle at Q. Then angle ACQ is called the ‘eccentric angle’ of the point P. … The two equations x = a cos , y = b sin are known as the parametric equations of the ellipse and ” is called the parameter.

What does conjugate mean in optics?

In optics, a conjugate plane or conjugate focal plane of a given plane P, is the plane P such that points on P are imaged on P. … In microscopy and macro photography, the subject is close to the lens, so the plane at which the image sensor is placed is said to be a finite conjugate.

What is conjugate position?

The object point and image point of a lens system are said to be conjugate points. Since all the light paths from the object to the image are reversible, it follows that if the object were placed where the image is, an image would be formed at the original object position.

Are conjugate lines wrt the circle?

If the pole of the line ax+by+c=0 w.r.t a circle lies on another line a1x+b1y+c1=0; then the pole of the second line will lie on the first and such lines are said to be conjugate lines.

How do you find the conjugate of a circle?

Conjugate Points: Two points P and Q are said to be conjugate points with respect to the circle S = 0 if Q lies on the polar of P. The condition that the two points P(x, y) and Q(x, y) are conjugate points with respect to the circle S = 0 is S = 0.

How do you find the conjugate of a point?

with respect to the point (x2,y2) and (x3,y3) can be calculated by taking the ratio k:1 as an external division i.e. the point which divides the line joining (x2,y2) and (x3,y3) in ratio of k:1 externally, is known as the harmonic conjugate of the given point (x1,y1).

What is conjugate angle?

Conjugate-angles meaning (geometry) A pair of angles that sum to 360 degrees.

What is diameter medical term?

[di-am-ter] the length of a straight line passing through the center of a circle and connecting opposite points on its circumference; hence the distance between the two specified opposite points on the periphery of a structure such as the cranium or pelvis.

What’s the eccentricity of an ellipse?

The eccentricity of an ellipse refers to how flat or round the shape of the ellipse is. The more flattened the ellipse is, the greater the value of its eccentricity. The more circular, the smaller the value or closer to zero is the eccentricity. The eccentricity ranges between one and zero.

What are the transverse and conjugate axis?

The transverse axis is a line segment that passes through the center of the hyperbola and has vertices as its endpoints. The foci lie on the line that contains the transverse axis. The conjugate axis is perpendicular to the transverse axis and has the co-vertices as its endpoints.

What is the conjugate axis?

: the line through the center of an ellipse or a hyperbola and perpendicular to the line through the two foci.

What is Auxiliary circle of hyperbola?

The Auxiliary circle of a hyperbola is defined as the circle with the center same as the hyperbola and with transverse axis as its diameter. The endpoints of the transverse axis are the two vertices of the hyperbola, so the circle also contains the two vertices of the hyperbola.

What is parabola and hyperbola?

Hyperbola. A parabola is defined as a set of points in a plane which are equidistant from a straight line or directrix and focus. The hyperbola can be defined as the difference of distances between a set of points, which are present in a plane to two fixed points is a positive constant.

What is auxiliary rectangle?

auxiliary rectangle of a hyperbola has vertices (-24, -15), (-24, 9), (10, 9), and (10, -15) and it has horizontal conjugate axis. close. The auxiliary rectangle of a hyperbola has vertices (-24, -15), (-24, 9), (10, 9), and (10, -15) and it has horizontal conjugate axis.
