Rationalize the denominator to simplify a trig expression

The video tutorial covers the process of rationalizing denominators, focusing on the use of conjugates. It begins with a review of rationalizing denominators in the context of the unit circle and triangles, then introduces the concept of conjugates, both irrational and complex, as a method to eliminate radicals. The tutorial includes a detailed example problem, demonstrating the application of conjugates and the difference of squares to simplify expressions. The session concludes with a practical example involving trigonometric functions, showcasing the simplification of a fraction using these techniques.
