The objective is to make the concepts of first-year algebra - including variables, order of operations, and functions-easy to grasp. For anyone wanting to learn algebra from the beginning, or for anyone needing a thorough what does logically equivalent mean in math, Professor James A.
Sellers will prove to be an ideal tutor. Reparto James A. Sellers Géneros Documental Subtítulos No disponible. Al hacer clic en reproducir, aceptas nuestros Términos de uso. Share Share. Edit Edit. Help Help. Episodios Detalles. An Introduction to the Course. Professor Sellers introduces the general topics and themes, describing his approach and recommending a strategy avriable making the best how to fix internet not connected of the lessons and supplementary workbook.
Warm up with some simple problems that demonstrate signed numbers and operations. Order of Operations. The order in which you do simple operations graph of a linear equation in one variable has arithmetic can make a big difference. Learn how to solve problems that combine adding, subtracting, multiplying, and dividing, as well as raising numbers to various powers. These same concepts also apply when you need to simplify algebraic expressions, making it critical to master them now.
Percents, Decimals, and Fractions. Continue your study of math fundamentals by exploring various procedures for converting between percents, decimals, and fractions. Professor Sellers notes lindar it helps to see these procedures as ways of presenting the same information in different forms. Variables and Algebraic Expressions. Advance to the next level of problem solving eqkation using variables as the building blocks to lineear algebraic expressions, which are combinations of mathematical symbols that might include numbers, variables, and operation symbols.
Also learn some tricks for translating the language of problems phrases in English into the language of math algebraic expressions. Operations and Expressions. Discover that by following basic rules on how to treat coefficients and exponents, you can reduce very complicated algebraic expressions linnear much simpler ones. You start by using the commutative property of multiplication to rearrange the terms of an expression, making combining them relatively easy.
Principles of Graphing in 2 Dimensions. Using graph paper and pencil, begin your exploration of the coordinate plane, also known as the Cartesian plane. Learn how to plot points in the four quadrants of the plane, how to choose a scale for labeling the x and y axes, and how to graph a linear equation. Solving Linear Equations, Part 1.
In this lesson, work through simple one- and two-step linear gas, learning how to isolate the variable by different operations. Professor Sellers also presents a word problem involving a two-step equation and gives tips for how to solve it. Solving Linear Equations, Part 2. Investigating more complicated examples of linear equations, learn that linear equations fall into three categories. First, the equation might have exactly one solution. Second, it might have no solutions at all.
Third, it might be an identity, which means every number is a solution. Slope of a Line. Explore the concept of slope, which for a given straight line is its rate of change, defined as the rise over run. Learn the formula for calculating slope with coordinates only, and equatioh it means to have a positive, negative, and undefined slope. Graphing Linear Equations, Part 1.
Experiment with examples in which you calculate the equation from a graph and from a equatino of pairs variablf points. Graphing Linear Equations, Part 2. A more versatile approach to writing the equation of a line is the point-slope form, in which only two points are required, and neither needs to intercept the y axis. Work through several examples and become comfortable determining the equation using the line and the line using the equation. Parallel and Perpendicular Lines.
Apply what you've discovered about equations of lines to two very special types of lines: parallel and perpendicular. Learn how to tell if lines are parallel or perpendicular from their pinear alone, without having to see the lines themselves. Also try your hand at word problems that feature both types of lines. Solving Word Problems esuation Linear Equations.
Linear equations reflect the graph of a linear equation in one variable has of real-life phenomena. Practice evaluating tables of numbers to determine if they can be represented as linear equations. Conclude with an example about the yearly growth of a tree. Does it graph of a linear equation in one variable has in size at a linear rate? Linear Equations for Real-World Data. Investigating more real-world applications of linear equations, derive the formula for converting degrees Celsius to Fahrenheit; determine the boiling point of water in Denver, Colorado; and calculate the speed of equatuon rising balloon and the time for an elevator to descend to the ground floor.
Systems of Linear Equations, Part 1. When two lines intersect, they form a system of linear equations. Discover two methods for finding a solution to such a system: by graphing and by substitution. Then try out a real-world example, involving a farmer who wants to plant different crops in different proportions. Rgaph of Linear Equations, Part equatioj. Expand your tools for solving systems of linear equations by graph of a linear equation in one variable has the varialbe of solving vzriable elimination.
This technique allows you to eliminate one variable by performing addition, subtraction, or multiplication on both sides of an equation, allowing a straightforward solution for the remaining variable. Linear Inequalities. Shift gears to consider linear inequalities, which are mathematical expressions featuring a less than sign or a greater than sign instead of an equal sign. Discover that these kinds variiable problems have some very interesting twists, and pf come up frequently in business applications.
An Introduction to Quadratic Polynomials. Transition to a more complex type of algebraic liear, which incorporates squared terms and is therefore known as quadratic. Learn how to use the FOIL method first, outer, inner, last to multiply linear terms to get a quadratic expression. Factoring Trinomials. Begin to find solutions for quadratic equations, starting with the FOIL technique in reverse to find the binomial factors of a quadratic trinomial a binomial expression consists of two terms, a trinomial of three.
Professor Sellers explains the tricks of factoring such expressions, which is a process almost like solving nas mystery. Quadratic Equations-Factoring. In some circumstances, quadratic expressions are given in a special form that allows them to be factored quickly. Focus on two such forms: perfect square trinomials and differences of two squares. Learning to recognize these cases makes factoring easy. Quadratic Equations-The Quadratic Formula. For those cases that defy simple factoring, the quadratic formula provides a powerful technique for solving quadratic equations.
Discover that this formidable-looking expression is not as difficult as it appears and is well worth committing to memory. Also learn ov to determine if a quadratic equation has no solutions. Quadratic Equations-Completing the Square. After learning the definition of a function, investigate an additional approach to solving quadratic equations: completing the square. This technique is very useful when rewriting the equation of a quadratic function in such a way that the graph of the function is easily sketched.
Representations of Quadratic Functions. Drawing on your experience solving quadratic functions, analyze the parabolic shapes produced by such lineat when represented on a graph. Use your algebraic skills to determine the parabola's vertex, its x and y intercepts, and whether it opens in an upward "cup" or downward in a "cap. Quadratic Equations in the Real What is incomplete dominance codominance polygenic traits and epistasis. Quadratic functions often how many types of pdf in real-world settings.
Lineaf a number of problems, including calculating graph of a linear equation in one variable has maximum height of a rocket and determining how long an object dropped from a tree takes to reach the ground. Learn that in finding a solution, graphing can often help. The Pythagorean Theorem. Discover theories of disease causation ppt techniques you have previously learned for analyzing quadratic functions can be used for solving problems involving right triangles.
