# Linear Algebra Done Wrong

### We will look at solving them three different ways.

**Linear algebra done wrong**.
Graphing substitution method and elimination method.

Differential equations in the form y pt y gt.
In this section we solve linear first order differential equations ie.
For example 2x3y5 is a linear equation in standard form.

Introduction askanyonewhyasquarematrixofcomplexnumbershasaneigenvalue andyoull probably get the wrong. We give an in depth overview of the process used to solve this type of differential equation as well as a derivation of the formula needed for the integrating factor used in the solution process. Topics range from number theory to relativity to how to study calculus. Solving systems of linear equations in three variables will cover systems that have three equations and three unknowns. As you can see the solution to the system is the coordinates of the point where the two lines intersect.

For example they can be sequences functions polynomials or matriceslinear algebra is concerned with properties common to all vector spaces. The standard form for linear equations in two variables is axbyc. In this tutorial we will be specifically looking at systems that have two equations and two unknowns. You now know what a transformation is so lets introduce a special kind of transformation called a linear transformation. The first four axioms mean that v is an abelian group under addition.

When an equation is given in this form its pretty easy to find both intercepts x and y. We already had linear combinations so we might as well have a. So when solving linear systems with two variables we are really asking where the two lines will intersect. It only makes sense that we have something called a linear transformation because were studying linear algebra. Books are recommended on the basis of readability and other pedagogical value.
