### Linear algebra

Linear algebra, sometimes hidden as a matrix theory, considers sets and functions, which maintain line formation. By doing this it covers the widest part of the math! So line algebra includes axiomatic treatments, arithmetic issues, algebraic structures, and even geometric elements; in addition, it provides tools used to analyze various scales, mathematical processes, and even physical conditions.

Linear Algebra contains matrix calculus reading. Legalize and provide a geometric definition of mathematical problem-solving. It creates an official link between matrix calculations and the use of line and quadratic conversion. Develops the concept of trying to solve and analyze line mathematical systems.

#### Use of Linear algebra

**Systems of Linear Equations**

We know that the equation of a straight line is spelled y = mx = + c, where m is the slope of the line (Tan of the line angle with x-axis) and c is the y-intercept (the distance when the straight line meets the axis of -y from the beginning). Thus the line at R2 (magnitude 2) can be represented by the sum of the form a1x + a2y = b (where a1, and a2 are not both zeros). Similarly, a plane at R3 (3-dimensional space) can be represented by the number of the form a1x + a2y + a3z = b (where a1, a2, and a3 are not all zero).

The line number in variables n n can be expressed in x1, x2,… .xn) ——– (1) (hyperplane in n)

##### Definition

A limited set of line statistics is called a line statistics system or a line system. The variables in the line system are called variables.

**Linear System with Two Unknowns**

If two lines intersect at R2, we get a system of line numbers and two unknown numbers Graphs for these figures are straight lines in plane xy, so the solution (x, y) of this program is actually the point of the difference between these numbers. lines. Note that there are three possibilities for a pair of straight lines on a xy-plane:

1. The lines may be parallel and distinct, where there are no crossroads and therefore no solution.

2. Lines may only cross one location, where the system has exactly one solution.

3. Lines may overlap, where there are many interlocking points (points in a common line) and as a result unlimited solutions.

**Consistent and inconsistent system**

A linear system is said to be inflexible if it has at least one solution and is said to be incompatible if it has no solutions. Therefore, a fixed two-line system of both unknown and unadulterated solutions has either one solution or more solutions – nothing more is possible.

**Reduced Echelon Form of a matrix**

In order to analyze the line mathematical system, we will discuss how to refine the algorithm to reduce the row. When using an algorithm for any matrix, we begin by introducing a non-zero row or column (i.e. it contains at least one non-zero element) in the matrix, the Echelon type of matrix.

A rectangular matrix is in the form of an echelon (or echelon line form) if it has the following three characteristics:

1. All lines of reason are greater than any lines of all zero

2. Each leading entry of the line is in the right-hand column of the front entrance of the top line.

3. Everything listed in the column below the front is zero.

**Row Reduction and Echelon Form**

If the matrix in echelon form satisfies additional conditions, then it is in a reduced echelon state (or reduced line echelon form):

4. The leading entry for each Enzo line is 1.

5. Each of the 1 leads is the only pointless entry in its column.

**Pivot Element **

A pivot is a nonzero number in place of the pivot used as needed to form a zero-by-line operation The line reduction algorithm consists of four steps, and produces a matrix in the form of an echelon. The fifth step produces a matrix in the reduced form of the echelon.
