Understand where the cofunction identities come from

The video tutorial explores various transformations of trigonometric functions, focusing on sine, cosine, tangent, and cotangent. It discusses how these functions can be transformed into one another through shifts and reflections, emphasizing the concept of cofunctions. The tutorial also introduces cofunction identities and demonstrates how to apply these transformations using graphical representations.
