Best tutor! dealing effectively with our stress! difficult stuff but easily explained. Enthusiasm on point! your smile makes me feel at easy; having all the confidence that iam truly learning something.
if you missed a letter not by accident, then you just said you don't know hindi well. its "your language", if you don't know english well. and if you don't know language please learn the culture first and the approriate phrases for situatuons otherwise it becomes awkward.
It seems that all of the trig function derivations use trig identities to get the limit function in a form that could be evaluated as h approaches 0. I've been taught that Trig Identities are also proven using Euler's Identity (e.g., e^ix = sinx + icosx) which is proven using Taylor series, which is derived from using derivatives of polynomials. Calculus is still at the root!
Very nicely done. I'd also run this through as d/dx cos x = d/dx sin (½π - x) = cos (½π - x) * d/dx (½π - x) = - cos (½π - x) = - sin x to give a really clear illustration of where the negative sign comes from on (only) the co-trig functions.
Thanks sir i a from India i was literally facing a lot of problems i derivatives but now i guess its interesting to learn tq sooo much one more question sir , where are you from?
h comes from the definition of the derivative and sin x is from the angle sum formula for cosine. That was something you learned in trigonometry or precalculus.
I am from Morocco, and although I do not know your language well, you are very good at explaining, good luck, teacher 💗😊

Thanks man you are now my maths tutor, I will be watching your video to learn ahead
Happy to help
You have a gift for explaining things in a way that's easy to understand, and I'm so grateful for that. Thank you for your help 🙏🙏
I'm from Bangladesh. I easily understand the math after watching your lesson.God bless you teacher😊
Glad to hear that
You are my best tutor,I enjoy listening to your lessons.
Thank you! 😃
Greatest math video I have ever watched, thank you so much
The way you follow steps,it's amazing.keep up
Thank you for the passionate teaching, it's really amazing and helpful. Beautiful handwriting.
loved ur teaching style sir!!was extremely helpful...once again thank you sir
Hello, I'm from the philippines. Nice teaching
Thanks for watching!
I have finished my class assignment with understanding. Thanks teacher.

Wow! This tutor na boss. You look Nigerian tho. I loved your teaching. Imma go check the others. You handwriting and smile is just ✨✨✨✨✨
Thanks. I am Nigerian
love everything about you, your style, teaching....🤩
Thank you
Excellently explained, 👍👍 keep it up sir.
Very nicely done.
I'd also run this through as
d/dx cos x = d/dx sin (½π - x) = cos (½π - x) * d/dx (½π - x) = - cos (½π - x) = - sin x
to give a really clear illustration of where the negative sign comes from on (only) the co-trig functions.
great energy, and great explanations and work through, thank you
Extremely helpful! Thank you so much!!!
You are wonderful teacher.
Great video!
Thanks Andrew. Hope you are rocking it over there!
Thank you! I hope that you are doing good as well!
Thanks sir i a from India i was literally facing a lot of problems i derivatives but now i guess its interesting to learn tq sooo much one more question sir , where are you from?
I'm glad it helped. I'm from Nigeria.
Best tutor ever 🙌🏿❤️🔥
I learnt a whole lot😊
Easy to understand😎
my question solved, thanks sir, god bless u.......
You just saved my life.God bless
totally different teaching style from nepal
I learned something new
Helloooooo, friend from afar. Thank you for the feedback.
@@PrimeNewtons 😊
It is a nice explanation ,,,,👏👏👏👏
You are a life saver!!!
Wow you are a magician thank you so much
Hey sir im from India🇮🇳 and i loved ur handwriting a lot!
Thank you for this video sir😊
You are carrying my math Jesus❤ thank youejjjeiwiiwwoow❤ I loveee youuuuuuu
This is great.. have been helped here 🙏🙏🙏. Thank you alot
Nicely done!
I wished i had come across your video a year ago. I wouldn't be needing to redo Engineering maths
really great sir
sir will you please do the derivative of cos^-1 x by 1st principle
Do you mean 1/cos(x) or arccos(x)?
@@PrimeNewtons yes sir but sir i need immeditaly
They are not the same. Tell me which one
arccos(x)
I dont know arccos(x). Only 1/cos(x) I know. I'll do a video later tomorrow.
Im from Sri Lanka , nice explanation
You are the best
Thanks
Nicely explained. But this your handwriting, I want to learn it
😊 Thanks
Wow thank you so much 🙏😘 you've been a helping a lot
من مصر جدا استفد من فيديوهاتك
great video, just have a question, why is sinH/H when h-->0 =1? wouldn't it just be 0?
Nice video Profesa
ALL I CAN SAY YOU KNOW YOUR STORY SIR.
Do you know in the books they have just did something that can't be understood human human interactions are always the best thank you so much sir
So many doubts cleared from your video 😢❤❤
Thnx sir that helped a lot
Nice explanation ;)
Wonderful I understand❤❤
Thankyou sir 😌 🇮🇳❤️🇳🇬
nice video sir but can you solve it by putting the limit as delta x instead of h
Yes. Just replace h with delta x.
@@PrimeNewtons thankyou sir i got it
Perfect video. Thanks a lot :)
Very nicely explained
Thanks. Very helpful
Thank you sir for your help I am glad tha i have such good teacher thank you sir
Is it just me or you’re just flirty as a teacher😂🤭 and your voice is nice too😌 Really great explanation btw❤️
Good job.
Great explanation!!
Where did you get the sin x and h
h comes from the definition of the derivative and sin x is from the angle sum formula for cosine. That was something you learned in trigonometry or precalculus.
Very useful, thank you
wow love this.
Sir I try to solve one more question using your method that is cos²x and get sin2x but the answer is -sin2x so please can you help me🙏
I don't understand your comment. What is the question again?
Thanks for this homie
it is easy and simple to comprehend
GREAT 👌
Very clear
Very helpful... Thank you
Thanks for the video ❤
this video made me subscribe
amazing video thanks
Hi sir , explain tan x also
As soon as I find time , I will do a video.
well explained
Nice sir
Please can you explain how sin0 divide by zero is 1 your were wrong
Thank you❣
Classic ❤
❤️
How did you get 1
😍😍
wow i like the videos
Thank you
awesome
I love you man
Thanks you❤
Thankyou sir
👍
Wooow thanks
Missed the proof of the identity to make the vid complete
Lucid!
i love you
I love you too
Well in the first step,he forgot to substitute cos x for f(x).
Uuuf why em i blushing
I didn't get

This is not a derivation from first principles. You only know the sinx/x limit from l'Hopital's Rule. Lame
😊 🫂 thanks
RESPECT FROM INDIA✨🤌
