Locus

Definition 3.1
The path traced by a moving point under some specified geometrical condition is called its locus.

## 1. Equation of a locus

Any relation in x and y which is satisfied by every point on the locus is called the equation of the locus. For example,
i. The locus of a point P ( x1y1) whose distance from a fixed point C(hk) is constant, is a circle. The fixed point ‘C’ is called the centre.

ii. The locus of a point whose distances from two points A and B are equal is the perpendicular bisector of the line segment AB.      Tags : Definition, Formula, Solved Example Problems, Exercise | Mathematics , 11th Business Mathematics and Statistics(EMS) : Chapter 3 : Analytical Geometry
