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.

How do the transformations of sine and cosine differ from those of tangent and cotangent?

What is the significance of reflecting functions over the Y axis?

What are R cofunction identities and how do they apply to trigonometric functions?
