# what is locus of a point

If you're posing a challenge whose answer you already know, say so explicitly in the body of the question (as comments are easily overlooked); the predominant assumption here is that a question is a request for help, so it's important to indicate when this isn't the case. The definition of a circle locus of points a given distance from a given point in a 2-dimensional plane. That means the calculated angle of G(s)H(s) at a point should be an odd multiple of ±180°. What is the locus of a point for which y = 0, z = 0? A locus is a set of points that meet a given condition. Example. Solution Show Solution. A locus is a set of points which satisfy certain geometric conditions. Concept: Three - Dimensional Geometry - Coordinate Axes and Coordinate planes. Many geometric shapes are most naturally and easily described as loci. For more Information & Topic wise videos visit: www.impetusgurukul.com I hope you enjoyed this video. We know that on x - axis both y = 0, z = 0. The given distance is the radius and the given point is the center of the circle.In 3-dimensions (space), we would define a sphere as the set of points in space a given distance from a given point. A locus is a set of points, in geometry, which satisfies a given condition or situation for a shape or a figure. If so, make sure to like, comment, Share and Subscribe! What is the locus of points that is symmetric points of A(1,3) according to the line y = mx + 2? Consider a line segment $$\overline{AB}$$. Mathematically speaking; locus is the path/surface, traced out by a moving point P which moves under under certain constraints (conditions) . $\begingroup$ Welcome to Math.SE! Before the 20th century, geometric shapes were considered as an entity or place where points can be located or can be moved. Оа 2 + y2 - 4x + 2 = 0 Ob. This signifies to be present on the root locus, the point must necessarily satisfy the angle condition. For example, given the point = 6 5 + 8 5, we can calculate the modulus as follows: | | = 6 5 + 8 5 = √ 4 = 2. For example, a circle is the set of points in a plane which are a fixed distance r r r from a given point P, P, P, the center of the circle.. The plural of the locus is loci.The area of the loci is called the region.The word locus is derived from the word location. Magnitude Condition: Further for the magnitude condition, the magnitude of both RHS and LHS must be equated for the equation G(s)H(s) = -1. A point moves in a plane so that its distances PA and PB from two fixed points A and B in the plane satisfy the relation PA-PB=k(k = 0), then the locus of P is View solution Through a fixed point ( h , k ) secants are drawn to the circle x 2 + y 2 = r 2 . The locus of a point for which x = 0 is (a) xy-plane (b) yz-plane (c) zx-plane (d) none of these 12 + y - 4y +2 = 0 12 + y2 - 2x - 4y = 0 Od r+ y - 2 y + 2 = 0 NO be 12 + y - y - 4 = 0 Another description of a parabola is as a conic section, created from the intersection of a right circular conical surface and a plane parallel to another plane that is tangential to the conical surface. The parabola is the locus of points in that plane that are equidistant from both the directrix and the focus. Let us place all points where each point is equidistant from A and B. The locus of a point is the set of all the points which satisfy a particular condition. Hence, The locus of points is a curve or a line in two-dimensional geometry. Recall that the modulus represents the distance of a point from the origin. Hence, the locus of a point for which y = 0, z = 0 is x - axis.
