Definition of Origin in Math. In mathematics, especially in the field of coordinate geometry; origin is said to be the initial point or the starting point from where we begin our calculations or measurements. On a ruler, the 0 is from where we start our measurements; hence it is said to be the origin of the scale.
Figure 2.1. Points and free vectors. pair (O; (e1; e2; e3)) consisting of an origin O (which is a point) together with a basis of three vectors (e1; e2; e3). For example, the standard frame in R3 has origin O = (0; 0; 0) and the basis of three vectors e1 = (1; 0; 0), e2 = (0; 1; 0), and e3 = (0; 0; 1).

1. Points at a Fixed Distance in Coordinate Geometry 617. For example, to write the equations of the locus of points 3 units from the horizon-tal line y 2,we need to write the equations of two horizontal lines, one 3 units above the line y 2 and the other 3 units below the line y 2.The equations of the locus are. y 5 and y 1.

vector starts at the origin O = (0,0,0), then the vector ~v = hp,q,ri points to the point (p,q,r). One can therefore identify points P = (a,b,c) with vectors ~v = ha,b,ci attached at the origin. Two vectors with the same components are considered equal if they translate into each other. This is equivalent that their components are the same.
MATH 22B Unit 10: Coordinates Introduction 10.1. Algebra is a powerful tool in geometry. In this lecture we circle back to the concept of coordinates and look also at other coordinate systems. We have introduced space as column vectors like [1;2;3]T. We can think of it as an arrow from the origin to the point (1;2;3).
The fibre of a map X!Zover a point pof Zis the inverse image of p, the set of points of Xthat map to p. The fibre of the projection X!A1 over the point x 1 = ais the set of points (a;b) such that bis a root of the one-variable polynomial f(a;x 2) = c 0xd+ c 1xd 1 2 + + c d with c i= c i(a). There will be finitely many points in this fibre ...
