Are sir aap itta efforts karte hai itta jyada aap hamare liye try karte hai ki well explained kare aur hum 👍 like na de 😄 are air u are such a humble 🧍♀️ dil se thanku sir 😊
no brother there are 4 formulas of cos2theta and very simple to use .. just check kro kee cos ka konsa formula use kre kee kuch common aajaye eqn me ya fir cancel ho jaye
For ex in dy /dt i have used the formula cos2t =1 -2 sin^2t But sir have used the formula cos2t =2cos^2 t -1 I m also so confused to use which formula and when to use it
Thanku so much sir..... really i always think where did you got this knowledge.... from which teacher I salute them and too you also again thanx alot 😍😊😊

This Question's calculation is very complicated like jethalal's life 😂😂😂

Who is he??
Easy h chotu
Bruh!! It’s just really exhausting how cos2theta has 100 different formula.. like how I’m gonna know which one to use😭😭😭😭
Wohi to bro

Sir, is it necessary to reach the textbook answer for exams or can we leave it as such? Will our marks get reduced if we do so?
i dont think its necessary unless u are asked to prove that dy/dx is equal to "some ans"
Bsdk wa sapna ayega kya ki kesa answer banana hai
@@parulpatel9179 right
It's necessary only if question says dy/dx = (some value)
Thank you
Sir jo LCM lia hai root cos2t toh wo bracket mai chala jayega na aapne ek term se multiply karke baaki dono term chhod di
Kuki baki wo multiply mei hai
Sir mai 10 th mai hoon just like kr ke ja raha hoon 😅🤣♥️🤗.....
I also

Comment bhi
Bhai 12me aao tb dekho yee video😅😅
Apka sawagat hi 12th mi 😶😶
10:00 sir yaha pr cos2t ka formula 1-2sin²t hota hai to apne 2cos²t-1 kese liya ?.....
Please samjha do
Cos2t=
1-tan²t/1+tan²t
1-sin²t
2cos²t-1
Ye teeno formula's cos2t ke hai ok!
It's very easy question ❤
Nature + study = 💯 focus 1:51
Just hearing this sound guys carefully
And also 5:19
And also 13:03
Long solution but easy calculation
Sir aapne pahale cos2t ka =1-2sin²t leya lakin dubara jab leya to =2cos²t-1 aisa kyo kya aak he lene sai answer same aayega formula to dono shi hai
Sir ye question logarithm se bhi ho sakta hai kya??
Sir ye question log method se jaldi ho jayega
Sir cos2t and sin2t ke formulae lgane se phle tak kre to thik h kya sir ?
Dhanyawad Sirji
sir...yeh log wale method se nhi ho skta???
Thank you sir, This question is very tough for me and you have explained it very easily and make this question to simple.
Thank you Dil se🙏🏻💖
Sir dy/dt mei _ phale se hee bahar tha, phir Hum _ common lenge phir ye positive nhi ho jayega kya 🙄🤔🤔🤔, please tell me sir 🙏
Isme trighusandipola derivative rule lag jayega
Same doubt .
Did you get it now?
Thanku sir ❤️❤️, you are the best teacher
The way you teach is the best way and u r the best👍💯 teacher . Thanks a lot for making such a helpful video.
Sir i think you are only math teacher in India who explain each and every word ❤❤
You are best teacher ❤
Thanku so much sir..... really i always think where did you got this knowledge.... from which teacher I salute them and too you also again thanx alot 😍😊😊
Sir can we differentiate this question by taking logarithm
Sir ise log se solve kr skte h kya
3 baar video dekh chuka hu and concept 80% aagya hai. Abb 1 ya 2 baar khud se practice krni pdegi fir aayega ache se
sin^2 t common aayeega na wrong step hai
Nice explanation sir👏👏👏👏👏👏
Sir agar ham sirf question simplify karenge toh exam main marks toh pure milenge na??
03:37 --> Have a Break... Have a Kit Kat.......
Har video ko like karta hu main sir 😊❤
Nice sir
Sir 5.10sec say 5.30 sec Tak copy nhii dikh rhi hai
sir very mst ❤❤❤❤ question
I like you nexa classes 🎉🎉🎉🎉🎉
Marks to miljayege na simply kiya hoga to ?
Guruji first ya second ko Aage Piche kar sakte hain kya ?
Sir ne video subah bnaya hoga 100% 😅

Thanks a lot sir for making such great efforts for us. You are really really the best teacher and your teaching style is just ausum❤❤
You are right
Ranveer maths sir is a good teacher
Sir,
this question will be asked in board exams?
I don't think it'll ask
Because this is too much lengthy
And as u know that almost lengthy question don't ask because lack of tym
Sir mere coaching me bhi ise method se bana hai ❤ maja aa gaya dubara dekh kar 😃😊
