= 1/2×2 cos6¶cos2¶
= Cos6¶cos2¶✓
Hope you understood 👍
मुझे advanced maths बिल्कुल भी नहीं आती है । और अभी तक कुछ भी नही आ रहा है मै बहुत परेशान हू क्यु की मुझे कोई ना कोई जल्दी से government job चाहिये मेरे घर की स्थिति बहुत ही जायदा खराब है
फिर भी मै आपकी सारी classes देखता हू।😭😭😭😭😭😭

2cosx cosy---- cos(x+y) +cos(x-y)
बहुत अच्छा पढ़ा रहे हो सर जी.. मज़ा आ गया देखकर.... बाकी सब तो वल्यू पुट करो ये करो वो करो ऐसे बताते हैं.. आपने तो बिल्कुल बेसिक से आसान कर दिया सब....एसएससी भी डर रही होगी कि अब कैसे सवाल बनाए जाए....😊✌️ आपको दिल से प्रणाम गुरु जी 🙏🙏 बस ऐसे ही हम पूरा एडवांस मैथ्स करा दो....🙏🙏

Sir mera edvance math apke besic class dekh ne ke bad mera Sara number ho raha he ....thank u so much sir ....
36:50 pe 2cosxcosy = cos x+y + cos x-y lga h likhne me mistake ho gyi baaki answer shi h

Sir please explain 2nd question by 1st method again
Thank you so much sir, mujhe sirf apka hi samajh ata h, baki teachers to kahi se v koi v point padhadete h, per aapki approach bht step by step h... Thank you thank you soo much 🙏🏼
Sir 6th main _sin5A _sin5A cancel kr dey but add karny thyyy
Sir 6th question m Apne -cos5 theta ko -cos theta se kse kaata
ha na same doubt ....can anybody explain please ??
Because Cos(-x)= cos x
So 2cos(3A/2).cos(13A/2)= cos 8A + cos 5A not -cos (5A)
As 2cosC cosD= cos(C+D) + cos(C-D)
sir could u please tell me this question is related which part from A to H point. at time 13:29 time.
Sir you are most genuine teacher on youtube... Thank you sir for precious efforts. 🙏🙏

your teaching style and guidance is awesome sir👌
Sir jb hum triangle ka area nikalte h to hum trigonometry (sin cos tan) ye sb kyu lgate hai..or konsi trigo term kis waqt lagegi
trigo ka use right angled ∆ me hi hota hai kewal.
sin= perpendicular(P) /hypotenuse(H) hota hai
cos = base(B) / H
tan = P/B .... hota hai
jab ksi right ∆ me P & H ki value pta hai tumhe to simply uska sin angle nikal lo , coz P, H ki maddad se sin nikalta hai ,
agar ksi ∆ me P , B ki value given hai ya angle given hai + B given hai & P nikalna hai to simply find tanθ
kuch help mili ?
Done sir ji😍
6 question sir ne sahi karaya bas pichhe vale part me
2cosx.cosy =cos (x+y) + cos (x-y) hoga
Mean last me + cos (5 theta) hoya jo
Starting ke - cos (5 theta) se kat jayega
And sir ne last vale part me
- cos 5(thita) likh diya jo ki
+ cos (5 thita) hona chahiye tha
Baki 6 q ka and correct h
6th question me 5thita kaise cancil hoga
