S1 E1 - An Introduction to Algebra II
3 मार्च 201132मिनProfessor Sellers explains the topics covered in the series, the importance of algebra, and how you can get the most out of these episodes. Then, launch into the fundamentals of algebra by reviewing the order of operations and trying your hand at several problems.The Great Courses Signature Collection या The Great Courses Signature Collection & Living सब्सक्राइब करें या खरीदेंS1 E2 - Solving Linear Equations
3 मार्च 201131मिनExplore linear equations, starting with one-step equations and then advancing to those requiring two or more steps to solve. Next, apply the distributive property to simplify certain problems, and then learn about the three categories of linear equations.The Great Courses Signature Collection या The Great Courses Signature Collection & Living सब्सक्राइब करें या खरीदेंS1 E3 - Solving Equations Involving Absolute Values
3 मार्च 201131मिनTaking your knowledge of linear equations a step further, look at examples involving absolute values, which can be thought of as a distance on a number line, always expressed as a positive value. Use your critical thinking skills to recognize absolute value problems that have limited or no solutions.The Great Courses Signature Collection या The Great Courses Signature Collection & Living सब्सक्राइब करें या खरीदेंS1 E4 - Linear Equations and Functions
3 मार्च 201129मिनMoving into the visual realm, learn how linear equations are represented as straight lines on graphs using either the slope-intercept or point-slope forms of the function. Next, investigate parallel and perpendicular lines and how to identify them by the value of their slopes.The Great Courses Signature Collection या The Great Courses Signature Collection & Living सब्सक्राइब करें या खरीदेंS1 E5 - Graphing Essentials
3 मार्च 201129मिनReversing the procedure from the previous episode, start with an equation and draw the line that corresponds to it. Then test your knowledge by matching four linear equations to their graphs. Finally, learn how to rewrite an equation to move its graph up, down, left, or right, or by flipping it entirely.The Great Courses Signature Collection या The Great Courses Signature Collection & Living सब्सक्राइब करें या खरीदेंS1 E6 - Functions - Introduction, Examples, Terminology
3 मार्च 201131मिनFunctions are crucially important not only for algebra, but for precalculus, calculus, and higher mathematics.

Discover that there are three possible outcomes: no solution, infinitely many solutions, and exactly one solution.The Great Courses Signature Collection या The Great Courses Signature Collection & Living सब्सक्राइब करें या खरीदेंS1 E8 - Systems of 2 Linear Equations, Part 2
3 मार्च 201130मिनExplore two other techniques for solving systems of two linear equations. First, the method of substitution solves one of the equations and substitutes the result into the other. Second, the method of elimination adds or subtracts the equations to see if a variable can be eliminated.The Great Courses Signature Collection या The Great Courses Signature Collection & Living सब्सक्राइब करें या खरीदेंS1 E9 - Systems of 3 Linear Equations
3 मार्च 201131मिनAs the number of variables increases, it becomes unwieldy to solve systems of linear equations by graphing. Learn that these problems are not as hard as they look and that systems of three linear equations often yield to the strategy of successively eliminating variables.The Great Courses Signature Collection या The Great Courses Signature Collection & Living सब्सक्राइब करें या खरीदेंS1 E10 - Solving Systems of Linear Inequalities
3 मार्च 201129मिनMake the leap into systems of linear inequalities, where the solution is a set of values on one side or another of a graphed line. An inequality is an assertion such as "less than" or "greater than," which encompasses a range of values.The Great Courses Signature Collection या The Great Courses Signature Collection & Living सब्सक्राइब करें या खरीदेंS1 E11 - An Introduction to Quadratic Functions
3 मार्च 201132मिनBegin your investigation of quadratic functions by visualizing what these functions look like when graphed. They always form a U-shaped curve called a parabola, whose location on the coordinate plane can be predicted based on the individual terms of the equation.The Great Courses Signature Collection या The Great Courses Signature Collection & Living सब्सक्राइब करें या खरीदेंS1 E12 - Quadratic Equations - Factoring
3 मार्च 201132मिनOne of the most important skills related to quadratics is factoring. Review the basics of factoring, and learn to recognize a very useful special case known as the difference of two squares. Close by working on a word problem that translates into a quadratic equation.The Great Courses Signature Collection या The Great Courses Signature Collection & Living सब्सक्राइब करें या खरीदेंS1 E13 - Quadratic Equations - Square Roots
3 मार्च 201131मिनThe square root approach to solving quadratic equations works not just for perfect squares, such as 3 × 3 = 9, but also for values that don't seem to involve squares at all. Probe the idea behind this technique, and also venture into the strange world of complex numbers.The Great Courses Signature Collection या The Great Courses Signature Collection & Living सब्सक्राइब करें या खरीदेंS1 E14 - Completing the Square
3 मार्च 201130मिनTurn a quadratic equation into an easily solvable form that includes a perfect square, a technique called completing the square. An important benefit of this approach is that the rewritten form gives the coordinates for the vertex of the parabola represented by the equation.The Great Courses Signature Collection या The Great Courses Signature Collection & Living सब्सक्राइब करें या खरीदेंS1 E15 - Using the Quadratic Formula
3 मार्च 201130मिनWhen other approaches fail, one tool can solve every quadratic equation: the quadratic formula. Practice this formula on a wide range of problems, learning how a special expression called the discriminant immediately tells how many real-number solutions the equation has.The Great Courses Signature Collection या The Great Courses Signature Collection & Living सब्सक्राइब करें या खरीदेंS1 E16 - Solving Quadratic Inequalities
3 मार्च 201130मिनExtending the exercises on inequalities from a previous episode, step into the realm of quadratic inequalities, where the boundary graph is not a straight line but a parabola. Use your skills analyzing quadratic expressions to sketch graphs quickly and solve systems of quadratic inequalities.The Great Courses Signature Collection या The Great Courses Signature Collection & Living सब्सक्राइब करें या खरीदेंS1 E17 - Conic Sections - Parabolas and Hyperbolas
3 मार्च 201132मिनDelve into the algebra of conic sections, which are the cross-sectional shapes produced by slicing a cone at different angles. In this episode, study parabolas and hyperbolas, which differ in how many variable terms are squared in each.

3 मार्च 201132मिनInvestigate the algebraic properties of the other two conic sections: ellipses and circles. Ellipses resemble stretched circles and are defined by their major and minor axes, whose ratio determines the ellipses' eccentricity. Circles are ellipses whose eccentricity = 1, with the major and minor axes equal.The Great Courses Signature Collection या The Great Courses Signature Collection & Living सब्सक्राइब करें या खरीदेंS1 E19 - An Introduction to Polynomials
