Trigonometric Functions and Their Properties

The video tutorial covers the graphs, domains, and ranges of major trigonometric functions: cosine, sine, tangent, secant, cosecant, and cotangent. It explains how these functions relate to the unit circle, their symmetry properties, and the concept of asymptotes. The tutorial also discusses the domain and range for each function, highlighting key points where the functions are undefined.
