Respected Ushank Sir, I just wanted to take a moment to express my gratitude for your incredible work and providing us this master piece, "Trigonometric functions" video. Your explanations, tricks, and tips really helped me understand everything better. From covering all concepts and doubts to providing us solutions. I used to struggle with this chapter, but now I feel much more confident, all thanks to you Sir. To my fellow juniors, don't miss out on watching this video for atleast two times before your finals. It's super helpful and game changer! Hats off to you Sir, and keep up the fantastic work!
Ek advice mere juniors k liye from a 2nd year senior who is pursuing her graduation in maths. Dekho iss chapters me jo jo bhi bare bare formulas bataye gaye hai kahi se bhi unko proof krna sikh lo isse tumhe clarity aa jayegi ki formula ban kaise raha hai or yaad rakhna bohot easy ho jayega. Warna ratta marte reh jaoge and believe me kitna bhi ratta mar lo yaad nahi hota 😅 Special Tip :- Compund Angle se formula se hi baki k sare formulas bhi derive hote h 😊 It is some extra work but its totally worth it 👍

Thank you sir for such comprehensive lectures I find this channel very informative. Quite curious about what are the additional benefits in purchasing the batches as these TH-cam lectures themselves are 100% beneficial. Hats off!
Literally itta accha kon pdhata h yrr... To the respected ushank sir You don't know that, you are the one who is gonna saving me in 11 th maths.. As I'm a PCMB student and tomorrow is my half yearly and I was so nervous because i don't study maths regularly and don't give tests of this subject. But but now I am confident. Lots of love and respect to you sir❤
2:44:39 i have better solution use tan2x formula you will get quadratic so there gonna be 2 solution so you need to take ve+ 22.5 come under 1 quad so it should ve+
Sirr Agar P=3,,B=4 AND we know ,ki ,value of H =5 Hypotenuse, perpendicular base yeh sab Toh. Yeh exam me ,pura solve karke likhna zaruri he ??? Ya directly we can solve and. Write
Fabulous, outstanding explanation. Words are being so less to describe your interest and creative way to explain things. like this sad story,,mindblowing efforts☺☺
Sir ji, 10th question in ex: 3.2 -> cot(-15xpi/4) = - cot(675) = - cot(90x7+45) = tan(45) [becuase 7 is odd]. But avery answer is showin cot(45). What am I doing wrong sir?
Sir I can also give u a trick. to solve value of Trig. Function. Jaise value of sin 31π/3. We. Can see the last and main part jo h π/3 aur sin π/3 ki value= √3/2
Sir you are a best mathematics teacher i ever seen in my life sir mughe mere coching or school ke teacher samgha samgha ke takh gaye liking mughe ghanta kuchh samgh nhi aya lekin thanks to you sir for this greatest session mast concept clear hua ❤

USHANK SIR - BEST MATHS TEACHER PADMASHRI AWARD GOES TO USHANK SIR 😎
1:39:20 wrong 🏁 tan 270 is not defined
You and Ashu sir are my most favourite teacher ever❤️🔥
1:21:10 Sir the actual correct question is sin²π/6 + cos²π/3 - tan²π/4 = - 1/2
Aree sir paper hai kl or aap video ko baar baar rokhne ki khe rhe ho 😂
thanku sir so much u are a great teacher tomarrow is my half yearly i had best revision ever
Respect for ushank sir ❤️
Great teacher ✨
Well explained ☺️

Cosx=B/H 58:51

Remind me by liking my comment 😂😂😅😅😂😂
Bhai pls continue
2:44:39 i have better solution use tan2x formula you will get quadratic so there gonna be 2 solution so you need to take ve+ 22.5 come under 1 quad so it should ve+
2:05:40 khol ke baith skte ho (formulae)💀
nhi bhai
naw
gandi baat😂
1:18:24 questions is sin^2 π/6 + cos^2 π/3 - tan^2 π/4 = -1/2
Positive - anticlock wise
Negative - clock wise😇
1:18:00
Ans of ques 10 ex 3.2 = 1
2:12:50 sir it should be tan x+y/2 😊
It is correct check ncert
Bro you should check for x-y there should be sinx-siny 😊
You can solve it
@@varunjamwal3182 I solved it and it's is correct as shown in question
@@PreetSingh-ql2pu but in my ncert book it is sinx -siny

Sirr
Agar P=3,,B=4 AND we know ,ki ,value of H =5
Hypotenuse, perpendicular base yeh sab
Toh. Yeh exam me ,pura solve karke likhna zaruri he ??? Ya directly we can solve and. Write
U have to show
It's important to show this step
Excellent one shot sir thank you so much sir
Fabulous, outstanding explanation. Words are being so less to describe your interest and creative way to explain things. like this sad story,,mindblowing efforts☺☺
Right 👍🏻
Ushank sir best maths teacher I have ever seen...❤
Ye best channel hai , aur kahi jaoge toh CHAANTE PADENGE 😂❤❤
2:03:30 This question can be simply solved by using a2 - b2 = (a+b)(a-b) identity in only 2 steps..👍🏻
Then why not sir?

Grand explanation 🔥🔥
No one will come here a day before exam ...of math*student is in mandir right now😮😮😮😮😮
Thnx, for clearing each and every doubt, especially those doubts which we ignore as silly question
Exercise 3.2 question no. 10 answer is 1
Best teacher ❤❤❤
Sir I can also give u a trick. to solve value of Trig. Function. Jaise value of sin 31π/3. We. Can see the last and main part jo h π/3 aur sin π/3 ki value= √3/2

1:26:06 sir it is cosec 60 not sec 60
30 degree bhi pi/6 60 degree bhi pi/6
Nhi, 30degree-pi/60 aur 60 degree- pi/30 (vo sir ne suru me galati se galat likh diya tha par baad me unhone sudhar bhi diya tha)😊
@@Anshu_rajput0987 bhai answer pata h mujhe maine bs correct kra tha, or ek baar timeline diyo kaha kra tha
@@manavvashist4215 achha
sir maza aa gya thank you for giving us guide about how to do
Sir ex 3.1 ke 6 question mai 60° or 75° ko radians mei kyo liya unko degree mai hi kyo nhi nikalwa ?
Because the theta has to be in radian measure to apply this formula. That's why u have to first convert the degree to radian to use the formula L=rQ
Thankyou so much sir for this BRILLIANT lectureeeee❤💫
Maja aa raha hai sir lecture me ❤
Sir you are legend of maths
Kya padhate ho aap ek dam shandar ❤❤
Sir cosec me square nhi hai..
