13. solve elementary problems in kinematics.

### Brief description

This module introduces some of the fundamental notions of geometry - points, lines, curves, planes and surfaces - analytically, in the language of coordinate geometry. Conics are classified in terms of their equations and geometric properties. The concepts of tangent and normal are developed.

### Aims

To develop geometric intuition and the ability to view geometric problems analytically and vice versa.

### Content

1. COORDINATE GEOMETRY IN THE REAL PLANE: The straight line. Loci. Conics - particular forms and the general form. Identification of centres, foci and major and minor axes. Cases of degeneracy. The general equation of the tangent. Families of lines and conics. Parametric plane curves. Tangents and the use of derivatives. Polar coordinates.
2. INTRODUCTION TO VECTOR METHODS: Unit vectors. Scalar and vector products, angles and orthogonality. Position vectors. Linearly independent vectors. Vector equations of lines and planes. Introduction to kinematics.
