Cramer's rule is a method for solving systems of linear equations. It uses determinants to find the solutions for the variables. For two equations with two unknowns, the solutions are found as the ratio of two determinants. For three equations with three unknowns, Cramer's rule can also be applied by writing the solutions as ratios of determinants. Some examples are provided to demonstrate solving systems of two and three equations using Cramer's rule.

CRAMER’S RULE
Kishan Kasundra presented on Cramer's rule for solving systems of equations. Cramer's rule uses determinants of coefficient matrices to find variables. It can be applied to systems with 2 or 3 equations. For 2 equations, the determinant of the original coefficient matrix and matrices with the coefficient columns replaced by the constants are calculated. The ratios of these determinants over the original give the variables. For 3 equations, a similar process is followed using a 3x3 coefficient matrix. An example showed applying Cramer's rule to solve a 2x2 system.

Gaussian Elimination Method
Gaussian elimination is a method for solving systems of linear equations. It involves converting the augmented matrix into an upper triangular matrix using elementary row operations. There are three types of Gaussian elimination: simple elimination without pivoting, partial pivoting, and total pivoting.

Pivoting strategies help prevent zero pivots and reduce round-off errors.

The graphical method involves plotting the equations on a graph and finding their intersection point. Cramer's rule uses determinants to solve for one variable at a time. Elimination of unknowns treats the equations similarly to how single equations are solved, by adding or subtracting equations to eliminate variables until one is isolated. Examples are provided for each method.

1. The document outlines the day's math lesson which includes reviewing systems of equations solutions, solving 3x3 systems, and completing yesterday's class work.
2. It provides examples and steps for solving systems of equations by graphing, elimination, and substitution. Equations are presented in standard form and slope-intercept form.
3. Solving 3x3 systems is discussed, noting they cannot be graphed since they exist in three dimensions. The substitution method is demonstrated through an example.
9.5 Nonlinear Systems of Equations
This document discusses methods for solving nonlinear systems of equations, including elimination, substitution, and graphing. It provides examples of solving systems by each method and writing the solutions as ordered pairs. Nonlinear systems contain at least one equation that is not linear. Elimination transforms equations so variables can be eliminated. Substitution solves one equation for a variable and substitutes into the other equations. Graphing can also show the intersection points that are the solutions. The document emphasizes being able to use any solving method and explains solutions may be irrational numbers. It concludes with assigning practice problems from the textbook.
Ultimate guide to systems of equations
i) The document discusses various methods for solving systems of linear equations, including graphing, substitution, elimination, and cross-multiplication.
ii) It also addresses solving systems that can be reduced to linear equations, such as transforming non-linear equations using substitution.
iii) Examples are provided to illustrate each method for deriving the solution of a system of equations.
Systems of equations alg1
This document discusses various methods for solving systems of linear equations, including graphing, substitution, elimination, Cramer's Rule, and Gauss-Jordan elimination. It provides examples of using substitution and elimination to solve systems of two equations in two variables. Substitution involves isolating one variable and substituting it into the other equation. Elimination involves manipulating the equations so that one variable can be eliminated when the equations are added together. Both methods result in a single equation that can be solved for the remaining variable.

0.3.e,ine,det.
This document discusses equations, inequations, determinants, and Cramer's rule for solving systems of equations.
It defines equations as statements with two expressions separated by an equal sign that have the same value. It discusses solving equations by manipulating expressions to isolate variables. Inequations are defined as equations containing inequality symbols like < or >. Determinants are defined as values corresponding to square matrices that describe properties like a matrix having the same determinant as its transpose. Cramer's rule is introduced as a method to solve systems of linear equations where the matrix of coefficients is regular, by calculating determinants of matrices formed from the system.
Quadratic Equations
Quadratic equations take the form ax^2 + bx + c = 0. This document discusses four methods for solving quadratic equations: factorizing, completing the square, using the quadratic formula, and graphing. It provides examples of solving quadratic equations with each method and emphasizes that practice is needed to master the techniques.

Digital clock
1. The document describes the design of a digital clock consisting of second, minute, and hour sections.
2. The second and minute sections use counter ICs to count from 00 to 59 before resetting. The hour section uses a different design to count from 00 to 11 before resetting.
3. The sections are assembled together and the completed digital clock is tested and found to operate smoothly showing the correct time.
Logic Simplification Using SOP
This document discusses simplifying Boolean expressions using Boolean algebra. It explains how to simplify expressions by applying rules like distribution, idempotency, etc. It also covers converting expressions to standard forms, including sum-of-products (SOP) and product-of-sums (POS). Standard forms make expressions easier to evaluate, simplify and implement. The document provides examples of simplifying expressions and converting between SOP and POS form.
Cramer’s Rule OF Matrix
Cramer's rule is a method for solving systems of linear equations. It uses determinants to find the solutions for the variables. For two equations with two unknowns, the solutions are found as the ratio of two determinants. For three equations with three unknowns, Cramer's rule can also be applied by writing the solutions as ratios of determinants. Some examples are provided to demonstrate solving systems of two and three equations using Cramer's rule.

This document discusses how color is an effective communication tool in branding and marketing. It lists the group members and their roll numbers who created the document at Superior University in Lahore. It then discusses how certain colors like red easily attract attention, black is used for emphasis, and green promotes naturalness and growth. The document emphasizes that color is a vital part of communicating a positive image for products in the marketplace. It explores the physiological and psychological impacts of color on people from early childhood. The power of color in learning environments is discussed, as color adds meaning and aids communication. The document concludes by noting that the brain sees and remembers colors first.

Cramer’s rule of matrix
- 2. Cramer’s rule is a method for solving linear simultaneous equations. It makes use to determinats and so the knowledge of these necessary before proceeding. INTRODUCTION
- 3. Cramer’s Rule - two equations If we are given a pair of simultaneous equations a1x + b1y = d1 a2x + b2y = d2 then x, and y can be found from Example Solve the equations 3x + 4y = −14 −2x − 3y = 11 Solution Using Cramer’s rule we can write the solution as the ratio of two determinants.
- 4. The solution of the simultaneous equations is then x = 2, y = −5. The solution set is {(2,-5)}
- 5. Cramer’s rule - three equations For the case of three equations in three unknowns: If a1x + b1y + c1z = d1 a2x + b2y + c2z = d2 a3x + b3y + c3z = d3
- 6. Exercises Use Cramer’s rule to solve the following sets of simultaneous equations. a) 7x + 3y = 15 −2x + 5y = -16 b) -x + 2y + 3z = -7 -4x - 5y + 6z = -13 7x - 8y - 9z = 39
