Basics of Analytical Geometry
BASIC CONCEPTS
1. Draw in a plane two mutually prependicular number lines x/x and y/y, one horizental and the other vertical.
2. The lines must intersect at real number "0" of both the lines.
3. The point of intersection is called "origin" and is denoted by "0".
4. The two lines are called the coordinate axes.
5. The horizental line x/0x is called x-axis.
6. The x-axis and y-axis has divided the plane into four parts, that are called "QUADRANTS". They are named Q1, Q2, Q3, and Q4.
7. now there is a point on the plane, through P draw lines parallel to the coordinate axis. MORE.....
