Trigonometric Quadrant Rule | Best trick | Class 11th mathematics 

It should be sin(180+theta)=-sin theta And I really appreciate the way u teach....u made this chapter so intresting ✌🏻& iam able to catch every thing that ur teaching... thanku sir!!

Sin(180+theta) equal -sin theta

After School to College was awesome Thank you sir

Cot(360-theta)= -cot theta Sir this video is very helpful 👍 and thank you so much for giving a lots of importants and examples☺️☺️☺️☺️

Really....yaar 👌 expln... sir so thanks fr this vdo...

गर्दा पढ़ाते है गुरुजी आप मज़ा आ गया ❤❤

•Mistake:- sin (180°+theta) = -sin theta •cot (360°-theta) = -cot theta •cos(270°) =cos180°+90°=-cos90°

Amazing sir thank you so much.

cot (360-θ)= -cotθ and sir i have one doubt you have been written sin(180+θ)=-cosθ but 180,360 wont change sir so the answer is -sinθ.....

thanks sir the way you teached did not bored me and today only i found maths interesting 😄

Sir cos theta in second quadrant is negative.. so how sin145 answer be same in both methods Signs changed

Cos(360-theeta)=-cot thita

What a wonderful video Sir

Thanks a lot of you. Apj abdul kalam sir

Sir sin (180+theta ) = sin theta right answer ye hoga or cot( 360- theta) = - tan theta

Sir, cot(360Deg.-Thita)= -cot Thita

Great sir really great 9 , 10 , 11 , 12 tkk trigonometry clear nhi hua tha aaj apke wajhe se drop mein aakar trigonometry clear ho gya lots of tnanks and love ❤️ you sir ❤️❤️✨️✨️

13:58 sir yaha pe -sin theta hoga kyuki in 4th quadrant sin is -ve....right?🤔

Great explanation sir 🔥

Thank you sir

Thankyou sir for always providing us the awesome content ......🙏🙏♥️🤗

Sir bahut mast padhaya

Sir ye video se mere quadrant rule bahut ache ho gye hai thank you so much sir 😊😊😊😊😊....helpful vedio tnq sir 😊😊😊😊

this cleared all my doubt thanks sir!

Thanks sir really helpfull❤

This helped me so much. I was very confused about this concept but now I am not. Thank you, sir!

Amezing sir.. Aapka jawab nahi 🥰🥰🥰😍

Superbbb sir you clear the all concepts of formula

Thanks

13:55 Sir cos (270 +∅) + kese hua ,4 quadrant main to cosec and sec hi postive hote hai

Aapse se padhne ke baad saare doubt clear ho gye 🤪🤪🤪Or aapne to mera dil khush kr diya sir

Thanks sir for great explanation❤

Best

Nice explanation sir Thanks for giving your valuable time Now I understand all

Thankyou sir, i loved your way of teaching in simple and clear way. I request you to upload more videos like this.

Sir bahut achhçhha smajhaye hai

Sin(180-∅)= -Sin∅ ayaga There is mistake on 15:40 in the video

Jabardast padhaai sar

Sir accounting to your teaching [ π, 2π ] no charge , so , this one sin(180+∅ ) = - sin . But your are wrote -cos.

Nyc explanation👌👌👌👍👍👍

hello sir video puri cansept samajh me aya

Cot 360 - theta = -cot theta Cos 270 = Co's 180 + 90 =- cos 90 =0

thank u sir....u cured my headache

15:39 cos nhi sin aayega

Very nice.... Thanks

Super 😊😊😊

THANKS SIR

Good

Sir the lecture was good but try to write big cause it not much visible to me❤

Sir aap Ka video dekhe laga ki online nhi offline padhi Kar Raha hu sir or video dale sir trigonometry Ka sir plzz

i like this fantastic

Best teaching

Gajab sir very nice

Can anyone explain why tan theta is positive in 3rd quadrant!?

Amazing session sir. For me this video is more than a treasure because it is the video after which I started watching you and you had made my faith.😍🤩😍🤩😍🤩

16:05 sir sin(180-A) toh not change hai naa woh toh -sinA aana chahiye

THANKYOU SO MUCH SIR

Thank you so much sir

Nice explaination 👏👏👏👏

Sec (270°- theta)=cos theta , not cosec theta

Thank you sir.

Sir your teaching style is so much awesome. your understanding trick is very easy. I am lmpresed of your teaching style.

Sir ajj apki video dekh ke mujhe mzzaa agya u know the trigonometry chapter is not there in term 1 class 11 therefore our teacher had not teached us this thing.. but he was continuesly telling bla bla bla it was going from my one ear to outside..but know watching your video I am really happy that I can also solve this type of problems thnku sir really a great thanka to you

bht ache se aa gyaa sir thank you mujhe trigo mein 12 mein bht problem aa rhi thi smjhne mein iske baad aa gyaa thank you sir

GREAT TEACHING

Concept pura clear ho gya sir ji

Thanks sir

You helped me when I needed it the most . Thanks !!!

Thanks sir , nice 👍

360+theta=-cot theta

thank you sir))))

sir COT(360-Q) = +COTQ.....wow i reallly really..really LOVE YOUR teaching style sirr....please sir can i have your contact?....aapne sach me boht accha padhaya ...mai apne class ka sabse AVERAGE baccha hu sir maths me..lekin aapki vdo dekhne ke baad...mtlb ab mujhe wo feel hi nii ho rahi...thank u so much sir...aapne boht easy lang. me samjhaya..

THANK YOU SIR ALL CONCEPTS ARE CLEARED ❤️❤️❤️

Life saver for last moment studying.

Cot(360degree-theta= - cot theeta

Sir u are wrong.. Sin(180+theta) equal to -sin theta. U have written it as -cos theta.. Which is wrong. At time 15:53

thanks Sir!🙌

Cot theta {360- theta } = - tan theta

best lecture on this topic

Sir super duper explanation

Thank you sir you helps me alot 🙂 I subscribed you

Great..thanksalot sir

TQ so much sir this class helped lot to me

Thank you so much sir 🙏🙏🙏🙏😊😊😊😊 I am so Happy

-cot theta and 2π won't change and its -sin theta

Such a nice video Sir🥺, You are brilliant sir, i wasn't able to understand trigo, but bcoz of u ,today I'm able to do it.. God will fulfill your all wishes.. Thank you so much sir🥺😭

Cot(360° -Q)= +cotQ

Thank you 🙏🏻

Sin(180°+Q) = -sin Q hoga

Nice explanation sir

Sir class 11 math ka elements solve ki video bnao sir 🙏plzz

Thankyou sir

Home work : cos ( 180 degree+90 degree) = 0

Thank you sir your lacture is very helpful me

Osm explaination sir 😀

you made this concept very easy for me , thankyou sir

Cos (270°)= cos (180°+90°) =cos 90° = 0 Am i right sir

🎉🎉😊😊10/10 ratting ❤❤

Great sir.....👍

Thankuh so much sir...
