Hyperbola https://www.youtube.com/watch?v=qzPj0aQIUTUA hyperbola is the locus of a point in a plane which moves in the plane in such a way that the ratio of its distance from a fixed point in the same plane to its distance from a fixed line is always constant which is always greater than unity.Standard equation of the hyperbola Let S be the focus, ZM be the directrix … [Read more...] about Hyperbola

Ellipse
Ellipse https://www.youtube.com/watch?v=9xSgKqTxZbgAn ellipse is the locus of a point which moves in such a way that its distance from a fixed point is in constant ratio (<1) to its distance from a fixed line. The fixed point is called the focus and fixed line is called the directrix and the constant ratio is called the eccentricity of the ellipse, denoted by … [Read more...] about Ellipse
Parabola
Parabola https://www.youtube.com/watch?v=yM0DSZ3yCNMA parabola is the locus of a point which moves in a plane such that its distance from a fixed point (i.e., focus) in the plane is always equal to its distance from a fixed straight line (i.e., directrix) in the same plane.Standard equation of the parabola Let S be the focus, ZZ' be the directrix of the parabola and … [Read more...] about Parabola
