Thank you sir from now i am your new student. Really i get tired 😫 to understand principal solution but due to you my concept of principal becomes crystal clear. Thank you so much 💓 💗 💛 💖 ☺️ ♥️ Really, amazing teacher and again thank you 😊 🙏🏻 ❤️ 😘...... Lots of love to you ❤️ 😍
Sir at 2:55:25 I think we should have done intersection instead of union because all the three equations must be simaltaneously true . Also if we consider x as 2π/3 then equation is not satisfying Cos2π/3 = -1/2 Cos 4π/3 = -1/2 Cos 6π/3 = 1 Adding them it becomes 0 So how can be x = 2π/3 is a solution ?????? I think intersection should be done here
Nhi bhai Uniun hi hoga kyoki jab tum n=1 rakhoge to teeno ka solution alag alag hai to values sabki 1 ho jayegi to ans 3 aa jayega,ok?????? REPLY IF YOU GET IT.
sir in question cosx + cos2x + cos3x = 3 , answer should be x=2npi as. Three of these conditions should satisfy simultaneously that it cosx =1 and cos2x = 1 and cos3x = 1. Thats when it will be three so . x = 2npi and x=npi and x = 2npi/3. so 2npi is the only common set here in three of them so answer should be 2npi.
I don't know whether I'll clear jee or not but I will try to distant myself from trigno as much as I can i just can't tolerate this just want to be successful in life and laugh at my younger self for not able to understand trigo
1:19:00 general solution Nikal ke n ka value put kare to nahi hoga Maine nikala to principal solution hi mila general solution se baki ke 2 solution nahi mila to -2pi and 2pi ke bich mai ataa ho
Sir matrices and determinant karado sir plzz my NDA exam is on 14 Nov but I want to learn with your sir because after understanding your concept aakho Mai chamak ajati hai 😅
Doubt **** Sir 2:04:00 par agar ham tan(π/2 - 5πsin@) ka formula lga de to neeche infinity ho jaayega than tan(5πcos@) =0 isse hm no. of solutions kyu nhi nikal sakte. ??? Someone please clear my doubt
Hello sir in Type 6; example number 5 there we can use simply technic. Sinx + 2 sin2x - sin3x = 3 Here, Sinx max value = 1 2Sinx max value = 2 Sin3x max value = 1 So finally,. 1 + 2 -1 not equals to 3 Hence proved that there is no solution! 🥰🥰 This technic I have learnt from you 🥰🥰🥰🥰🥰🥰

Are bhai unacdemy app download class krlo aur nv sir ko follow krlo sir ke saare special class dekh sakte ho yha pdhane ke baad sir practice session lete h free class ke liye bhi
3:16:20 sir if we use the logic sinx=1 sin2×=1 sin3×=0 we get 3sols and no other combination is possible as they gave (0,pie) interval,where am i wrong sir??
sinx =1 ke solutions pie/2 aur sin2x= 1 has solutions pie/4 and 5pie/4 in range (o,pie) par brother hmme common solution chahyie jis par simultaneously sinx=1 ho aur sin2x=1 ho tumne union le liya solutions ka jabki hme solutions ka intersection lena tha

Hello sir in Type 6; example number 5 there we can use simply technic.
Sinx + 2 sin2x - sin3x = 3
Here, Sinx max value = 1
2Sinx max value = 2
Sin3x max value = 1
So finally,. 1 + 2 -1 not equals to 3
Hence proved that there is no solution!
🥰🥰 This technic I have learnt from you 🥰🥰🥰🥰🥰🥰
Sin3x=0 pe satisfy hogi eq but further sol krke no solution ara
