Poincar´e’s Disk Model for Hyperbolic Geometry

This result is now know as the Saccheri-Legendre Theorem (Theorem 7.3). He was unable to arrive at a contradiction when he looked at ... Note that this arc is clearly orthogonal to Γ by its construction. ... The hyperbolic trigonometric functions cosh(x) and sinh(x) are defined by: sinh(x) = ex −e−x 2 cosh(x) = ex +e−x 2 and tanh(x ...

CHAPTER 8: MATRICES and DETERMINANTS

SECTION 8.1: MATRICES and SYSTEMS OF EQUATIONS PART A: MATRICES A matrix is basically an organized box (or “array”) of numbers (or other expressions). In this chapter, we will typically assume that our matrices contain only numbers. Example Here is a matrix of size 2 3 (“2 by 3”), because it has 2 rows and 3 columns: 10 2 015

x is an n 1 vector. A system of linear equations , also referred to as linear map, can therefore be identi ed with a matrix, and any matrix can be identi ed with ("turned into") a linear system. In order to study linear systems, we study matrices and their properties. 2 Matrices 2.1 Basic Matrix Operations and Properties Consider two n ...
