This document lists and defines vocabulary words from math lessons on various topics:
- Direct, inverse, joint, and combined variation define relationships between variables that can be written as equations involving a constant of variation.
- Rational expressions are quotients of polynomials. Complex fractions contain fractions in the numerator and/or denominator.
- Rational functions are functions whose rules can be written as a ratio of two polynomials. These may be continuous or discontinuous.
- Radical expressions involve a variable within a radical, or root. Rational exponents are exponents that can be expressed as a ratio of integers.
- Piecewise functions combine one or more functions over different intervals. Step functions are constant over each interval.
Logarithms and logarithmic functions
Logarithms relate an input value to the power needed to raise a base to produce that output value. Logarithmic scales are used to measure sound because they match how humans perceive changes in loudness. The key properties of logarithms are:
1) Logarithmic functions are inverses of exponential functions.
2) When working with logarithms or exponents, it helps to rewrite the problem in the other form.
3) For logarithmic equations, setting the arguments equal is valid if the bases are the same.

1. Homework Task 3 on systems of equations and inequalities is due on August 6. Students should check all memos on the online learning platform.
2. The document discusses finding inverses of matrices and solving matrix equations. It provides examples of finding the inverse of 2x2 and 3x3 matrices using elementary row operations to transform the matrices into an identity matrix.
3. Solving a system of equations using a matrix inverse involves writing the system as a matrix equation AX=B, then multiplying both sides by the inverse of the coefficient matrix A to isolate the solution vector X.
Simplifying radical expressions, rational exponents, radical equations
This document discusses simplifying radical expressions using the product, quotient, and power rules for radicals. It also covers adding, subtracting, multiplying, and dividing radicals. Rationalizing denominators is explained as well as solving radical equations. Key steps include isolating the radical term, squaring both sides to remove the radical, and checking solutions in the original equation.
Abs regression
This document presents an introduction to simple linear regression. It defines regression as finding a functional relationship between variables, with simple regression involving two variables - an independent and dependent variable. Linear regression finds a straight line relationship between the variables, while non-linear regression finds a curve-line relationship. Simple linear regression fits a straight line to the data using an equation that predicts the dependent variable from the independent variable. Regression analysis allows modeling and exploring relationships between variables and can be used for prediction and understanding spatial patterns.
7.6 solving logarithmic equations

2) Exponential equations with different bases, which require using logarithms and properties of logarithms to isolate the variable.
3) Logarithmic equations, where the variable can be inside or outside the logarithm. These also use logarithm properties and are rewritten as exponential equations to solve for the variable.

- The formula for the cross product is derived using determinants. Two methods - using cofactors or copying columns - provide the formula.
- The direction of the cross product follows the right-hand rule and is orthogonal to both original vectors, unless they are parallel.
- The cross product can be used to find a vector orthogonal to a plane defined by three points, and to determine if three vectors lie in the same plane.

The document then discusses finding the complementary solution through the characteristic equation for 1st and 2nd order differential equations. It also covers finding the particular solution depending on whether the right-hand side is a polynomial, exponential, or combination of exponential and trigonometric terms. An example circuit problem is worked through to demonstrate the process.

Pythagorean Proof
The document provides a proof of the Pythagorean theorem. It constructs a right triangle ABC with sides of lengths a, b, and c. It extends the sides to form a larger square with side length a+b. This creates 4 right triangles within the larger square. Equating the total area of the larger square to the sum of the areas of the 4 triangles and the square on hypotenuse c yields a2 + b2 = c2, proving the Pythagorean theorem.
A presentation on mathematics
The document discusses the origins and definitions of key terms and concepts related to circles. It defines a circle as a set of points equidistant from a fixed point and notes the Greek origins of the word. Common circle terms are defined, such as radius, diameter, chord, arc, sector, and segment. The circumference and area formulas are presented. The constant pi is discussed as the ratio of circumference to diameter and its importance in mathematics.
Properties of geometrical figures
The document discusses using GeoGebra to construct and investigate the properties of various geometric figures. Students will work in pairs using GeoGebra to construct shapes like rectangles, squares, triangles, parallelograms, and rhombuses. They will explore the defining properties of each figure and use a "drag test" to determine if their construction is accurate or just a drawing. The goal is for students to better understand geometric shapes and constructions through an interactive activity using dynamic geometry software.
Lines And Angles
This document defines and explains various geometric terms including:
- Point, line, line segment, ray
- Types of angles such as acute, obtuse, right
- Relationships between angles such as adjacent, vertical, complementary, supplementary
- Properties of angles and lines cut by a transversal, including corresponding angles, alternate angles, and interior angles
- Theorems regarding the sum of angles formed when a ray stands on a line, vertically opposite angles, parallel lines cut by a transversal, and lines parallel to the same line.
Practical geometry for class 8th
This document discusses how to construct quadrilaterals given certain measurements. It provides examples of constructing quadrilaterals when given: 1) four sides and one diagonal, 2) two diagonals and three sides, 3) two adjacent sides and three angles, 4) three sides and two included angles, and 5) other special properties. Step-by-step instructions and diagrams are used to demonstrate constructing specific quadrilaterals based on given measurements.
Properties of Real Numbers
The document discusses properties of real numbers. It defines real numbers and distinguishes between rational and irrational numbers. Rational numbers can be expressed as ratios of integers, while irrational numbers have non-terminating, non-repeating decimals. It also outlines relationships between subsets of real numbers and properties that real number operations satisfy, such as commutativity, associativity, identities, inverses, and distribution.

Quadrilaterals
1) A quadrilateral is a geometric figure with four sides, four angles, and two diagonals. The sum of the angles is always 360 degrees.
2) There are six types of quadrilaterals: trapezoid, parallelogram, rectangle, rhombus, square, and kite. A parallelogram has both pairs of opposite sides parallel. A rectangle has one right angle. A square is both a rectangle and rhombus with all sides equal.
3) Theorems include: the diagonals of a parallelogram bisect each other; if the diagonals of a quadrilateral bisect each other it is a parallelogram; a quadrilateral is
polynomials class 9th
This document discusses polynomials and some key concepts related to them. It defines what a polynomial is and explains that they can be categorized as monomials, binomials, or trinomials depending on the number of terms. It also discusses the degree of a polynomial, which is the highest power of the variable. Other topics covered include standard form for writing polynomials, the remainder theorem, and the factor theorem.
ARITHMETIC PROGRESSIONS

The concepts taught here will be used in every math class you take from here on. Well introduce you to some exciting stuff like drawing graphs and solving complicated equations. Since we are learning Algebra, Geometry in the school days. But the is a real life application of Algebra which is used in Geometry. Now a days the social media has improved a lot. We cant able to solve those figured puzzles, hence we can solve them by using algebraic equations. S. Ambika | R. Mythrae | S. Saranya | K.
