- Contents
- Linear algebra.
Elementary analytic geometry. - Reference texts
- K.W. Gruenberg and A.J. Weir, Linear Geometry. GTM, Springer-Verlag, New York, 1977.
- Educational objectives
- Acquisition of the geometrical thought through algebraic tools.
- Prerequisites
- Polynomial factorizations. Solutions of the algebraic equations of the first and second degree. Binomial and trinomial equations. Equations solvable by applying Ruffini's rule. Elementary analytic geometry in the plane. Trigonometry.
- Teaching methods
- Frontal lectures. Almost all results will be rigorously proved with the exception of those concerning projective geometry and algebraic curves. At te same time many exercises will be presented and solved.
- Other information
- Attendance is not mandatory but highly recommended.
- Learning verification modality
- Two hours of class-work with 8 exercises: 4 exercises about linear algebra one of which involving a finite field; 2 exercises about elementary analytic geometry in the space; 2 exercises about the sphere and/or the circle in the space. Then fifteen/thirty minutes of oral examination.
