This video tutorial provides a comprehensive guide to graphing trigonometric functions, including sine, cosine, tangent, secant, cosecant, and cotangent. It begins with basic graphing techniques for sine and cosine, then explores transformations such as shifts and stretches. The tutorial progresses to more advanced examples, including graphing secant and cosecant using reciprocals, and concludes with techniques for graphing tangent and cotangent. The video is structured with timestamps for easy navigation.
