Simplify Trig Complex Fractions

The video tutorial covers complex fractions, focusing on using the least common denominator (LCD) to simplify them. It also delves into trigonometric identities, particularly the Pythagorean identity, and demonstrates how to rationalize denominators using conjugates. The tutorial includes examples of multiplying by conjugates to achieve the difference of squares and concludes with a final example involving trigonometric fractions.
