He goes over useful strategies, proves each identity, and then shows how to find the general restrictions (in radians) for each. • This lesson is an important lesson for anyone proving identities! • You can see the list of all 34 identities I give to my Advanced Functions students here: https://bit.ly/grade-12-trig-identities
