Trigonometry Identity: 1 + cot^2(x) = csc^2(x)
Показать описание
In this video I go over the proof of another trigonometry identity and this time prove the identity: 1 + cot^2(x) = csc^2(x). The proof for this is similar to the identity proof in my last video, and involves simply dividing both sides of the basic Pythagorean Identity sin^2(x) + cos^2(x) = 1 by sin^2(x) instead of by cos^2(x) as I did in my last video.
