A little talk on Sine, Cosine and Tangent || in Hindi for Class 9
In this Mathematics video in Hindi for Class 9 we talked about Sine, Cosine and Tangent. In short these are named as sin, cos and tan.
These apply to a right triangle.
sin θ = opposite/hypotenuse
cos θ = adjacent/hypotenuse
tan θ = opposite/adjacent
In this video we talked about the fundamentals of these trigonometric functions and we also discussed on how to use these functions.

Sir thanks , its sad that there are not as many views as this wonderful video deserves. You have explained it very well, absolutely nailed it. I was looking for something like this from few days and it has cleared all my doubts. Sir thanks again, you come to the level of a student to make it clear and it is the best part of your teaching method. Thanks very very much...
Thanks a lot sir.. it's really helpful and trigonometry is interesting.
Method of teaching is very impressive 🙏🙏
Very well explained Sir. Thanku so much. 🙏🙏🙏🙏
Amazing after 50 year of my life you have clear my concept
THANK YOU,SIR for improving our coming future .. 🙏🙏
Thank you So much Sir. It had comfused me a lot but with your teaching I have understood the concepts👍. Once Again THANK YOU SO MUCH SIR!! 😊
Thank you sir. It was really helpful...
Thank you sir so much I have complete my FSC but still I was confused in this topic thank you sir so much ❤😂🎉🎉😂❤❤❤🎉🎉
Thanks ❤sir this video is way made way to easier and easy to understand 😉. Every video on this concept has a complicated result expect this one🙏👍
Sir your teaching style is very good and first time I love little bit maths.
Aap kya cheej hai sir Aap ko khud Nahi pta Aap ko best teacher ka award jarur milna chahiye 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻
Unbelievable video for quick learner's
I never thought that one person learn me so easily
Thnx sirr , now i understand this concept very well thnku 🎉🎉😊😊😊💖❤❤❤
What a great teacher sir
You are really great sir.
Thanks sir It was very helpful to me
U made it very very very interesting gor me sir so, Am leaving physics of class 9 for 2 days and going to read trigonometry broadly😁😁
Thank you so much sir🙏🙏
Aap mahan kam karte hai sir.

Mera banaya maths videos koi nahi dekhta... May be I am not good enough. I started creating Maths videos, then I had to stop. Not many students were interested. Views - negligible Audience retention - horrible.

Sir aapke edu point ke physics ko dekhkar . maine 2018 mein 12th ke physics mein 79 Marks laya... wo bhi sirf 15 days he maine dekha tha... maine aapke channel ko December 2017 mein subscribe kiya tha .... as "bhadwa makhan" . Aapka sir padaane ka tarika best hai sir.. Aapka lecture kabhi horrible nahin ho sakta...

Good work, it would be better if you should have talked about on the Ration and relationship as trigonometry is all about ratio and relationship between the triangle's sides. and more is that how an angle can be equal to a value, it means angle is nothing but a value derived from the relation of the sides. I would write a relationship like that Cos theta= adjacent:hypotenuse.

Good thinking. It would be better if you revisit the concept of ratio. Ratio can be representes as x:y or x/y. Both are the same. And angle is not derived from anything. It is an independent quantity. That is why it is included in the extended base quantities. It is an entirely different story that you can interrelate angles and the lengths of the sides of a right triangle. Learn, learn, learn.... Grow your concept.....
Great sir

Sir, sin of 45 degree 2/4root = root2/2 hona chahiye n.
Wahhhhh wahhhhhhh👍👍👍👍🙏🙏🙏🙏🙏
Sir ye jahan b banaengy to same e distance banega jahah b ?
Nice
Sir basically me poochna ye cha raha hon k ,sin or cos physically kya bata rahy hoty hain hamain For example ham agr hypotenuse ki direction me move karain to ,ya horizontally se move kar k vertical direction me move karain ,to sine or cose hamain kya batain gy????????????
For right angle how fix opposite and adjacent
Sr isko yad karna padega ya solve wase samjh m a gya...
Good
Sir tangent trigonometry me kyu vo tho circle me hota he na?
I have got understood the trigonometric functions through this video but I have a question 👇👇
☺❤❤❤
Sir plz plz plz answer aapne jo ye sin ki table banayi hai isme values fix kyu hai jaise 30° mein aapne √1÷4 hi kyu liya aur kuch kyu nahi liya aur plz answer 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏

Sir why sin theta = p/h❓
This teacher sounds like my professor at University of Illinois at Chicago (UIC). I would sit next to him in a classroom of 300 students due to the accent.

In case of 90, sin 90 means ek triangle me do right angle, how to take intuitive feel of this.....
@edupoint.secondary
3 жыл бұрын
Make theta = 85° Then 86° Then 87° and so on upto 90°. You will get the feeling. For 90° the opposite side will be equal to the hypotenuse. Hence, sin 90° = 1 For 90° adjacent vanishes. Hence, cos 90° = 0.
Sir ye sine , cosine,tangent kha se aaya hai sir
