The video tutorial focuses on simplifying a trigonometric expression involving secant and tangent functions. The instructor begins by identifying potential simplification strategies, such as using the Pythagorean identity and factoring by grouping. The process involves grouping terms, factoring out common factors, and applying the identity to replace secant squared terms. The final expression is simplified to a product of terms, and the instructor concludes by discussing the limitations of further simplification.
