The video tutorial covers the concept of reference angles in trigonometry, explaining how they can be used to create right triangles and evaluate trigonometric functions such as sine, cosine, and tangent. The instructor demonstrates the process of drawing central angles and using the Pythagorean theorem to find side lengths. The tutorial also includes a step-by-step guide to calculating the six trigonometric functions, including their reciprocals: cosecant, secant, and cotangent.
