The video tutorial covers the concept of cosine using the SOHCAHTOA method, setting up a triangle problem to find missing sides using the Pythagorean theorem. It simplifies the square root of 24 to 2√6 and calculates the six trigonometric functions: sine, cosine, tangent, cosecant, secant, and cotangent. The tutorial also explains how to rationalize denominators for these functions and concludes with a Q&A session to address student questions and clarify concepts.
