Hi guys! This videos discusses how to prove trigonometric identities. We have different categories for the fundamental trigonometric identities such as reciprocal relations, pythagorean relations and ratio relations. We will learn how to represent a specific trigonometric function in terms of another trigonometric function by using these fundamental identities. We will also practice solving how to prove trigonometric identities by making both sides of the equation the same again with the use of fundamental trigo identities. Happy learning and enjoy watching! #math #tagalog #trigonometry #provingidentities
