Or, for access to this single video, go to: http://www.mindbites.com/lesson/1238-pre-calculus-solving-trigonometric-equations This lesson will teach you how to solve equations involving trigonometric functions. Professor Burger shows you two ways to look at these equations, on a graph, and using reference angles. You will learn to rephrase the equation to determine what it is really asking, ""What value of X makes the function of X = n?"" You will learn how to write your answer to indicate infinitely many solutions and the step-by-step process of solving the equations. Examples of problems covered in this lesson involve trig functions, roots, fractions, variables and coefficients, including problems like cos x = 1/2 and sinx = -(2^(1/2)/2). You'll also learn when and why most trig problems like these have multiple (or infinite) solutions and how to correctly identify and denote these solution sets. This lesson is perfect for review for a CLEP test, mid-term, final, summer school, or personal growth! Taught by Professor Edward Burger, this lesson was selected from a broader, comprehensive course, Precalculus.
