In this lesson, the instructor shows how to prove two trigonometric identities using fundamental and Pythagorean identities. The left-hand side of the identities are simplified first and then transformed using algebraic steps to match the right-hand side. The instructor emphasizes that there isn't just one way to prove a trigonometric identity as long as the algebraic steps and identities used are correct. Overall, this lesson shows that with a good understanding of the fundamental and Pythagorean identities, anyone can prove trigonometric identities.
