I love the conversion into cos^2 - 1 = -sin^2; my usual approach is the double angle formulae cos^2 - 1 = 2 sin^2, which feels more tricky than the approach you gave.

Thank you. There's a lot of helpful information on your channel that I can watch and learn from. I'll be sure to check it out.
Nice and clear. Thanks for sharing.
Glad it was helpful! Thank you so much!
Thank you so much!!
It is my pleasure!!!
Difficult to read, no focus and numbers too small.

maybe because you are watching on an flip phone
This proof is complex jeez
It seems my explanation was a bit complicated. I'm sorry about that. I'm still a beginner TH-camr and have a lot to learn. I hope you understand.
it is not complex at all, its just beginner level limits and trigonometry
It's good I understand it in one go
