Fixed line of parabola
WebProve that the locus of a point, which moves so that its distance from a fixed line is equal to the length of the tangent drawn from it to a given circle, is a parabola. Find the position of the focus and directrix. Medium Solution Verified by Toppr Let AB be the fixed line, and O be the center of the fixed circle. WebIt is a straight line located at the opposite side of parabola’s opening. Vertex is the point extremity of parabola, i.e. highest point for open downward, lowest point for open …

WebOct 5, 2024 · An equation of a parabola is one in which a point on the curve is equidistant from a fixed point and from a fixed-line. The fixed point is called the parabola’s focus, and the fixed line is called the directrix of the parabola. In addition, it is important to note that the fixed point does not lie on the fixed line.
WebA parabola is defined as a collection of points such that the distance to a fixed point (the focus) and a fixed straight line (the directrix) are equal. But it's probably easier to remember it as the U-shaped curved line created … richard kloak attorney chicagoWebA parabola is defined as the set of points that are equidistant from both the directrix (a fixed straight line) and the focus (a fixed point). This definition may be hard to visualize. Let's take a look.
