The expression obtained for cosine is expanded by binomial expansion upto two terms (1-x)^1/2
He should have told that in lecture .🤣
Thanks

Hi, thank you very much for sharing your thoughts. I understand now. Keep safe everyone and, God Bless Us All Always. 🙏
And i think that the last term in the expansion is maybe neglible, so he doesn't write it anymore.
cos (a) = 1 - sin^2(a/2)
Isn't that sin(alpha)= O2G/O1G. Bcoz sin means ratio between opposite angle and hypotenuse. So, it should be O1G??
In 6:41 How you write the value of cos(alpha) ?
need proper explanation for "Cos value" ..
Here the side O1G is not perpendicular, actually It is Base (The side contains angle and right angle).
cos alfa ki value kese likh di aise hi shi se dekho asie to vha 4xsquare aana cahiye
he used cosx expansion taylor series
😡
Sir, please explain how we got cos a, In denominator how it came 8 x2,
Bro that's the comment section where you'll not find any solution about your query I personally don't recommend this channel to you.
7:15 4x^2 hoga
Cos(a)=√1-sin^2(a)...man
cos(x) = 1 -x^2/2! Is expansion of cos alpha
Kuc b pdha rh hai bhai
So poor writing work write at least a little bigger specially in diagrams
Nice sir ❤️👍
Comment me jawab Bhi dediya karoo ...sir
Brilliant clssThanQ
Get first two components of taylor serios of cosx see below link for talor expansion of cosx
kuch bhi samjh nhi aya
sir
