### College Algebra: Decoding the Circle Formula

watch full lesson here: http://www.mindbites.com/lesson/785-college-algebra-decoding-the-circle-formula This lesson is part of a series: College Algebra In this lesson, you will learn how to find the (x, y) coordinates for the center of a circle graphed on the Cartesian coordinate system as well as the the radius of the circle from a formula or expression that doesnt easily lend itself to the standard circle formula (e.g. r^2 = (x-h)^2+(y-k)^2)). To do this, you'll generally use a math technique called, Completing the Square. 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.
