Here you will learn how to find the focus of parabola with examples. Let’s begin – Focus of Parabola Coordinates (i) For Parabola $y^2$ = 4ax : The coordinates of focus is (a, 0). (ii) For Parabola $y^2$ = -4ax : The coordinates of focus is (-a, 0). (iii) For Parabola $x^2$ = 4ay : […]

Here you will learn formula for finding the equation of directrix of parabola with examples. Let’s begin – Equation of Directrix of Parabola (i) For Parabola $y^2$ = 4ax : The equation of directrix is x = -a. (ii) For Parabola $y^2$ = -4ax : The equation of directrix is x = a. (iii) For

Here you will learn formula to find the length of latus rectum of parabola with examples. Let’s begin – Latus Rectum of Parabola A double ordinate through the focus is called the latus rectum i.e. the latus rectum of a parabola is a chord passing through the focus perpendicular to the axis. In the given

Here you will learn what is the parametric equation of all forms of parabola and their parametric coordinates. Let’s begin – Parametric Equation of Parabola and Coordinates (i) For the parabola $y^2$ = 4ax : The parametric equation is x = $at^2$ & y = 2at. And parametric coordinates are ($at^2$, 2at). (ii) For the

Here you will learn some parabola examples for better understanding of parabola concepts. Example 1 : The length of latus rectum of a parabola, whose focus is (2, 3) and directrix is the line x – 4y + 3 = 0 is – Solution : The length of latus rectum = 2 x perp. from

Here, you will learn general equation and formulas for conic sections and formula to distinguish between conic. Conic Sections A conic section, or conic is the locus of a point which moves in a plane so that its distance from a fixed point is in a constant ratio to its perpendicular distance from a fixed
