### College Algebra: Solving Permutation Problems

http://www.mindbites.com/lesson/812-college-algebra-solving-permutation-problems In this lesson, you will learn about permutations and how to solve combinatorics problems that involve mathematical permutations. In math, permutations are distinct ways in which a set of numbers (or objects) can be ordered or sequenced. In evaluating permutations, factorials are used. Factorials in math are represented by the '!' sign (n-factorial is denoted by n!). You will learn to solve problems like, If there are 4 people in a race, how many different ways could these four people place? Also, you will be able to answer How many different ways could the top-2 finishers turn out (ignoring the sequencing for the third and fourth place finishers)? For Professor Burger's lesson on combinatorics problems involving combinations, check out http://www.mindbites.com/lesson/813. Taught by Professor Edward Burger, this lesson was selected from a broader, comprehensive course, College Algebra. This course and others are available from Thinkwell, Inc. The full course can be found at http://www.thinkwell.com/student/product/collegealgebra. The full course covers equations and inequalities, relations and functions, polynomial and rational functions, exponential and logarithmic functions, systems of equations, conic sections and a variety of other AP algebra, advanced algebra and Algebra II topics. Edward Burger, Professor of Mathematics at Williams College, earned his Ph.D. at the University of Texas at Austin, having graduated summa cum laude with distinction in mathematics from Connecticut College. He has also taught at UT-Austin and the University of Colorado at Boulder, and he served as a fellow at the University of Waterloo in Canada and at Macquarie University in Australia. Prof. Burger has won many awards, including the 2001 Haimo Award for Distinguished Teaching of Mathematics, the 2004 Chauvenet Prize, and the 2006 Lester R. Ford Award, all from the Mathematical Association of America. In 2006, Reader's Digest named him in the "100 Best of America". Prof. Burger is the author of over 50 articles, videos, and books, including the trade book, Coincidences, Chaos, and All That Math Jazz: Making Light of Weighty Ideas and of the textbook The Heart of Mathematics: An Invitation to Effective Thinking. He also speaks frequently to professional and public audiences, referees professional journals, and publishes articles in leading math journals, including The Journal of Number Theory and American Mathematical Monthly. His areas of specialty include number theory, Diophantine approximation, p-adic analysis, the geometry of numbers, and the theory of continued fractions. Prof. Burger's unique sense of humor and his teaching expertise combine to make him the ideal presenter of Thinkwell's entertaining and informative video lectures.
