The video tutorial covers graphing trigonometric functions, focusing on sine, cosine, tangent, cotangent, cosecant, and secant. It explains the defining points and rotational perspective of these graphs, introduces the concept of rubber-stamping for graphing, and discusses the signs of functions in different quadrants. The tutorial also provides practical examples and techniques for graphing these functions, emphasizing the importance of understanding the period and amplitude of each function.
