ANALYTICAL GEOMETRY
INTRODUCTION

In this unit we will approach the study of the straight line in a plane considering thoroughly the necessary concepts to do so.

We will be working with numerical and geometric elements to find algebraically the concepts associated with the study in a plane.

In some places geometry will be contemplated where it can be shown how an analytical method can be used to simplify geometric concepts.

OBJECTIVES
  • To understand the concept of a vector and to use them analytically.
  • To obtain the equation of a straight line in the plane in its different forms.
  • To determine the position relative to two lines of the plane.
  • To find the size of angle which they form.
  • To calculate the distance between two points, a point and a line and between two lines in the plane.
  • Apply the vector calculation to solve simple geometric problems: mid point of a segment.
  • Develop adequate flexibility to approach geometric situations form different view points.
  • To find the equations of some geometric loci.
