In this lecture we will discuss some ways in which systems of linear equations arise, how to solve them, and how their solutions can be interpreted geometrically. Linear equations: line in R2 (2-dimensions) can be represented by an equation of the form a x + a y = b. 2. (where a 1, a2 not both zero).
Linear algebra is the study of linear sets of equations and their transformation properties. Linear algebra, sometimes disguised as matrix theory, considers sets and functions, which preserve linear structure.
1. Systems of linear equations We are interested in the solutions to systems of linear equations. A linear equation is of the form 3x 5y + 2z + w = 3: The key thing is that we don’t multiply the variables together nor do we raise powers, nor takes logs or introduce sine and cosines. A system of linear equations is of the form 3x 5y + 2z = 3 ...

Lecture 1. 1 Systems of linear equations. Linear systems. A linear equation in variables x1; x2; : : : ; xn is an equation of the form. a1x1 + a2x2 + ¢ ¢ ¢ + anxn = b; where a1; a2; : : : ; an and b are constant real or complex numbers. The constants ai is called the coe±cient of xi, and b the constant term of the equation.
