Happy teachers day sir My teacher just started trigonometry and I couldn't understand anything. and whats the use of it

what you have shown @6.22 is basically Plimton 322 en.wikipedia.org/wiki/Plimpton_322 its a Babylonian clay tablet and it has Pythagorean triples and not trignometric ratios

Thanks Sir 🙏

THANKS SIR

Love u sir thnx

i m very thankful to u u do a very great job

13 books, not 12 books

No aryabhatt discover trigonometry long before they did read his book aryabhatia

Tri: triangle Gono: earth Metry : geometry

From where did they get the names sine cosine tangent? What is the origin of these names. This vdo is just like many other conventional videos on the eeb where no logic is told. Bsss ratt lo aur aage bdh jao..

Dessert caravan music plz

no offense but i understand not a single word. if the title is english, maybe the video should be too!

Thanks for sharing..
