@@HarshithJEE brother, ‘preciate the fact that you’ve done the same but god knows how many of those just understood the concept and how many didn’t, each child is different..some need these kinds of tricks to learn and talking about killing time? Dude this trick can solve questions just like that. You got no authority of saying anything to this teacher who’s come up with such a good way of teaching all kinds of people.

Please reconsider what you said.
I appeal to the teachers to kindly AVOID this form of teaching... Figuring out ways to memorize is bad especially, when one can teach the same topic intuitively. Sin theta defined as opposite side divided by hypotenuse of a right angled triangle. Sin 0 -- theta is zero, when opposite side to theta is almost zero. Therefore sin 0 is 0. Sin 45 -- theta is 45 when opposite nd adjacent are equal which implies hypotenuse is √2.. Therefore sin 45 is 1/√2 Sin 90, theta is 90 when opposite and hypotenuse are almost equal. Therefore sin 90 is 1. Sin 30, when hypotenuse twice as the opposite side which is evident from the geometry. Sin 60, similar to sin 30, hypotenuse is twice as of adjacent. Which means opposite/ hypotenuse is √3/2. Guys, please take a look at the geometry and intuitively and logically build these... Memory hooks as such won't take us far.

@@periyarmulti4934 while I understand your concerns, this is a great way to get kids into math. Especially useful for those with learning disabilities.

this is the perfect way to teach maths rather than mugging up how confident was mam when she was explaining it really loved the video also her smile while teaching was really satisfying
She is awesome! Specially because she teaches confidence. Of course this trick she shows is really great. Nevertheless, in my opinion pure memorization is also of value for those students that have good sight and/or sound memory. A good teacher must certainly know that not all are make equal.

@Vibhor Verma I'm sorry sir but I don't like maths ! But I found this trick really good!!! and it's okay if someone is teaching maths or any subject in their own ways ! (Again no hate)
AT MY OLD AGE I FIND THE VIDEO IS VERY INTERESTING AND INFORMATIVE. THIS REMINDS ME THE GOOD OLD DAYS OF MY SCHOOL. LOT OF THINKS TO THE TEACHER FOR SUCH INNOVATIVE WAYS OF LEARNING. OUR RESPECTED PRESIDENT & BELOVED TEACHER DR. A.P.J.A.KALAM ALSO MENTIONED THE NEED OF CREATIVE & INNOVATIVE APPROCH AT JUNIOR SCHOOL.
There’s some good teacher willing to teach their students from simple basic take more of her time to let them forever remember even when they are old , I personally have some good Teachers even in secondary level she felt surprised that most of us don’t really understand how to use nouns , tenses I remember she teach us from very basics English even until I am old I still guide those don’t really how to use proper English and I am glad in my life I felt great and firm , is not how good we are is we must be solid of ourself understand the correct rule no matter how difficult we are sure of ourself and I believe teacher wants her student to know and see things easily if they understand the way thanks to them 🙏🙏🙏🙏🙏
this video reminded me of my english teacher who taught us with the same excitement,it is good to see that some teachers actually focus on connecting with children rather than making us write the formulae and mug it up..the school teachers only want to finish the syllabus
syams Sss I’m sure it helps those who need or want to use them in future. Just my opinion- I’m a Prof in Linguistics so trig was definitely a waste of my time. Wish they allowed students to choose. I guess I didn’t have a choice because I was an Arts AND Pure Science student.
It's not a waste my friend... It is a boon to human being.. Trigonometric applications range from an atom to the whole universe... Even being a medico, I m still wondering on the beauty of mathematics, especially trigonometry, differentiation, integration, coordination geometry, and many more...........NB: I was one of Maths Olympiad...
Salute to this lecturer. Our trigonometry lecturer's teaching was not able to understand anything to whole class, when we said that we could not understand anything, the reply was you people should get adjusted to my teaching ☹️
Mam super man, I'm 45,but still interest in maths, but I'm driver, happy listen your class, instead of watching some videos waste of time, thankyou mam, the students who got you will enjoy the class, success in life, God bless you
There's an easier trick which I used to remember all the ratios. Note :- This took me only one minute to remember the ratios when I initially did it. Remember only first 5 ratios of sine theta to be able to remember the entire table For example, Sin0 = 0 Sin30 = 1/2 Sin45 = 1/√2 Sin60 = √3/2 Sin90 = 1 Once you remember these five, you can pretty much remember the entire table For example, Then reverse the order of sine theta to get the cosine ratios That is, 1, √3/2, 1√2, 1/2, 0 Now, we know tanA = sinA/CosA So to get tan0° , it must be sin0°/cos0• Which is 0/1 = 0 Similarly, you can get all tangent ratios Now you can reciprocate all the ratios For example 1/sinA = cosecA 1/sin45 = cosec45 Cosec45 = √2 Similarly, 1/cosA = secA 1/tanA = cotA I hope this trick is helpful for you..
i do the same but i get confused sometime ;-; but i guess if i remember her technique to then i can use your and her technique together to remember it perfectly
No way man! The best teachers in India always use English or American text books (foreign authors) to teach their classes. Refer me an Indian High School math text book compared to Mary P. Dolciani's, you will be hard pressed. No wonder India is country full of illiterate babas, homeopathy, astrology and fake scientists.
Rubi Theresa, you're the best math teacher I've ever seen. Can you come to America and get our young students back on track. Common Core isn't the Answer. Thank you for sharing your knowledge with humanity.
Great teaching. Indian education system would be boosted up magically if each and every school in India had YOU. Hats off Ma'am. Live long and create intelligent.
I wish this lady was my math teacher, thank you for explaining so clearly and actually going indepth to give your students keywords to tune into to remember. super helpful
What a sincere students these are I can't never this as my class. Also the way this teacher is explaining means its absolutely perfect. No words for this class. GREAT.
For imparting the values of Sine, Cos and Tan for angles 30, 45, 60 and 90 so many ways are there yet this is also appreciable as she strains herself very much to drill it in the minds of students...

how's it feels to be left-handed
*dies*
left-handed, stimulate your sense
The trick can be applied with both hands though
What if I don't have fingers?
Damn damn.... This tr is the true GANSTA tr.... Plus her high pitch voice and shouting in middle middle has got all this stuff in my mind.. And the palm method is lit... Too good tr.. I hope all tr be like u... Teaching with a smile and teaching right.... U r amazing... Truly.. 💯💯💯💯💯🙏
She’s a wonderful teacher, so encouraging and positive. She so enthusiastically wants every student to do very well.
Response of her students is enough for her as a MATHEMATICS teacher
Yea.....some students just sit there like a corpse staring at the teacher. That's really annoying...
Ma'am, the world needs teachers like you! Your students are blessed. 🙏🏾
You are so kind
@@RubiTheresa nabmar
The people who disliked were teachers who didn't know this technique.
Wish I had got such a high patience teacher while in school.Hats off to her patience in teaching ,without missing to show even a single step and speaking without taking break 👌
one of the finest teacher I saw in my life .
Those people who disliked this video are those who don't like maths !!!! 😂 (Just a fun thought no hate) mam really nice teaching!!! thankyou👏👍
@Vibhor Verma I'm sorry sir but I don't like maths ! But I found this trick really good!!! and it's okay if someone is teaching maths or any subject in their own ways ! (Again no hate)
@Vibhor Verma bro why is she calling ur dad in 2:34
Everyone need this kind of maths teacher....match will be fun. 🤯🔥🔥
AT MY OLD AGE I FIND THE VIDEO IS VERY INTERESTING AND INFORMATIVE. THIS REMINDS ME THE GOOD OLD DAYS OF MY SCHOOL. LOT OF THINKS TO THE TEACHER FOR SUCH INNOVATIVE WAYS OF LEARNING. OUR RESPECTED PRESIDENT & BELOVED TEACHER DR. A.P.J.A.KALAM ALSO MENTIONED THE NEED OF CREATIVE & INNOVATIVE APPROCH AT JUNIOR SCHOOL.
I swear I wouldn’t learn all this in 11 minutes from a regular teacher.
Amen to that! I sucked at Math... but if I had a teacher like her... i would've been in a different situation

How beautiful handwriting she has
Hrithik roshan would get confused as he has two thumbs... Good explanation Rubi madam.
Hahahahaha
thankyou so much mam , I learnt this method in my 10th class, When i used to fear these values , now I am in 12th and came back for revision.
Dislikers are of byzu's and Vedantu's students
If made the Art which is in your profile than u r great artist
Exactly
Everyone has a voice today, this mam is better in some ways than vedantu. HOPE U UNDERSTAND
I liked it and I am a Byju's student😂
😂😂😂
Man, I bow in utter respect & touch your feet. Teachers are the most influential element of the society. God = Gurus like you.
There’s some good teacher willing to teach their students from simple basic take more of her time to let them forever remember even when they are old , I personally have some good Teachers even in secondary level she felt surprised that most of us don’t really understand how to use nouns , tenses I remember she teach us from very basics English even until I am old I still guide those don’t really how to use proper English and I am glad in my life I felt great and firm , is not how good we are is we must be solid of ourself understand the correct rule no matter how difficult we are sure of ourself and I believe teacher wants her student to know and see things easily if they understand the way thanks to them 🙏🙏🙏🙏🙏
She's an amazing teacher. I just love how she emphasizes and how passionate she is about the topic👍up
Be positive...what a teacher...
And the pitch and accent reminds me of sir APJ
Yes she is from Tamil Nadu as Dr. APJ does. Hence, both speak TN's English accent. :)
Beautiful ❤️
India needs teachers like her 🙏🏻
*She* :- trying to teach by heart ❤️
*Other teachers* :- teaches for formalities ! 🤐
True
That is true
Nor for formalities
For*SALARY*
True
I try to do that too..teach math from the heart😊 ❤️
this video reminded me of my english teacher who taught us with the same excitement,it is good to see that some teachers actually focus on connecting with children rather than making us write the formulae and mug it up..the school teachers only want to finish the syllabus
She’s awesome! Its been 25 years and I still don’t understand why I had to learn trigonometry🤨 What a waste of high school ☹️
syams Sss I’m sure it helps those who need or want to use them in future. Just my opinion- I’m a Prof in Linguistics so trig was definitely a waste of my time. Wish they allowed students to choose. I guess I didn’t have a choice because I was an Arts AND Pure Science student.
@@sharonjohn9430 you didn't pursue higher eduction from India right? Cause till the nep they didn't allow mixing of streams
@@sike8358 I’m not from India. Singapore😁I’m sure half my ancestors were.
It's not a waste my friend... It is a boon to human being.. Trigonometric applications range from an atom to the whole universe... Even being a medico, I m still wondering on the beauty of mathematics, especially trigonometry, differentiation, integration, coordination geometry, and many more...........NB: I was one of Maths Olympiad...
Your phone works on trigonometry. Electricity works on trigonometry, every electronics are basically trigonometry functions
I'm im 12th rn and today i finally learnt all the values 🙂🙃
😂😂😂
Tell me the value of sin15° using the hand trick😂😂
@@mysticdragonex815 😂😂
#psychologypoint♥️
@@mysticdragonex815 easy.. just use sin(A-B) formula and the answer is (√3-1)/2√20.258
Salute to this lecturer. Our trigonometry lecturer's teaching was not able to understand anything to whole class, when we said that we could not understand anything, the reply was you people should get adjusted to my teaching ☹️

Mam super man, I'm 45,but still interest in maths, but I'm driver, happy listen your class, instead of watching some videos waste of time, thankyou mam, the students who got you will enjoy the class, success in life, God bless you
God bless her... she is so good and humble towards her students, and so passionate about her job...
Thank you
@@RubiTheresa Thank you very much ma'am... can you please tell what to do for TAN..? Means trick for TAN.
@@hmm675 please see the description box
There's an easier trick which I used to remember all the ratios.
Note :- This took me only one minute to remember the ratios when I initially did it.
Remember only first 5 ratios of sine theta to be able to remember the entire table
For example,
Sin0 = 0
Sin30 = 1/2
Sin45 = 1/√2
Sin60 = √3/2
Sin90 = 1
Once you remember these five, you can pretty much remember the entire table
For example,
Then reverse the order of sine theta to get the cosine ratios
That is, 1, √3/2, 1√2, 1/2, 0
Now, we know tanA = sinA/CosA
So to get tan0° , it must be sin0°/cos0•
Which is 0/1 = 0
Similarly, you can get all tangent ratios
Now you can reciprocate all the ratios
For example 1/sinA = cosecA
1/sin45 = cosec45
Cosec45 = √2
Similarly, 1/cosA = secA
1/tanA = cotA
I hope this trick is helpful for you..
S Sehgal ....... l also use the same trick..🤓
i do the same but i get confused sometime ;-; but i guess if i remember her technique to then i can use your and her technique together to remember it perfectly
@@chiranjeeviavulamanda2709 even I used the same
Same here
I also
Awesome explanation.... this teacher should be given a national award and also an opportunity to train other mathematics teachers. 👍🙏
Madam teachers like you will make Mathematics easy. Fear for Mathematics will vanish forever because of teachers like you.
Hatsoff madam.
I wish I’ve a math teacher like her when I was in my 10 standard. I wouldn’t have face a problem in trigonometry
Miss, I'm from Kerala. I stopped studying trigonometry for a while as I wasn't able to remember these .It really helped me. Thank you miss
Me too
Indian teachers are the best. Having studied in the US, IMO what we see here is all hype!
Are u from us
Yeah
Not alllllll
No way man! The best teachers in India always use English or American text books (foreign authors) to teach their classes. Refer me an Indian High School math text book compared to Mary P. Dolciani's, you will be hard pressed. No wonder India is country full of illiterate babas, homeopathy, astrology and fake scientists.
@@benoysarkar8368 you can prefer rd sharma or rs aggarwal brother
Rubi Theresa, you're the best math teacher I've ever seen. Can you come to America and get our young students back on track. Common Core isn't the Answer. Thank you for sharing your knowledge with humanity.
God bless these teachers who whole heartedly helped students ...❤️❤️❤️. Hope I was also having her as my maths teacher
The thing I haven't even understanded in a whole year,
you just cleared this concept in minutes...
I wish I could study in ur class
Great teaching.
Indian education system would be boosted up magically if each and every school in India had YOU.
Hats off Ma'am.
Live long and create intelligent.
We are Indian I like people like you who knows to admire.Md.Hussain.
WOWW What a Teacher. hatts of to her. I want this type of teacher for my son who s very very weak in maths.
I wish this lady was my math teacher, thank you for explaining so clearly and actually going indepth to give your students keywords to tune into to remember. super helpful
Thank you
We need such type of teacher in india
This teacher has divine enthusiasm to teach !
I can feel her positive energy radiating from her. What an excellent teacher and I'm sure she's a wonderful human too. Hats off mam 👍
This teacher is a real gem !!!
May god bless her.
This is a reminder to show that this was how class was being taken before the pandemic
What a sincere students these are I can't never this as my class. Also the way this teacher is explaining means its absolutely perfect. No words for this class. GREAT.
Mam you should be awarded the worlds best teacher award you are a very nice and good teacher.
This teacher made me remember my maths teacher..even she used to teach like her..very nicely..literally got her vibes
she is such a great teacher honestly, thank you for this trick.
AGH I NEED A TEACHER LIKE THIS- LITERALLY EVERY TEACHER SHOULD TEACH THE MANNER SHE TEACHES, THANK YOU SO MUCH MA'AM.
Agree, teachers like her will make math more interesting
Why do I find armies everywhere... 😂😂😂
For imparting the values of Sine, Cos and Tan for angles 30, 45, 60 and 90 so many ways are there yet this is also appreciable as she strains herself very much to drill it in the minds of students...
Thank you for explaining in English. You are really helping us out a lot!
Today is my maths class 10 pre board. I was struggling to remember values. You just taught me in no time. Thank you teacher
All the best🤣
