I understand that some of u guys this sir is doing wrong or never seen that formulae ... Normally we use F(x)-f(a)/x-a and we solve it by subt.. But here it is the orginal formula which also give same result like normal but it will be long for values of x other than zero so i recommend u to follow sirs method for x=0 or normal one if x have other values
BUT you should first check that the function is continuous at x=0!! for example if the second function in the piecewise is f(x)= 5 the whole function will satisfy your rules but it is not differentiable at x=5 because simply it is not continuous at that point.
@rootcat643 English isn't the universal language at all. Grow up. You think the moment you step out of india, everyone will be speaking english 😂 but learning english is kind of a must for us Indians especially...
Thank you. but how is (4-4)/h as h tends to 0 possible? i see it gives 0/0 which is undefined? let us dive into this again.
than you
If h is very-very small it approaches zero. Thanks
Very good. Thanks 👍

Sir i think ,that you wrote wrong formula ..
The formula of LHD is f(a-h)-f(a)/-h..
life saver, thank you mister Kumar!
all I can comment is..... may lord bless you you have assisted more students
Thanks. Best Wishes to you also!
Great
Sir ,Should we check differentiability for a derivative or for a function?
Should we check it for a derivative of a function??
@@yogeshr5754 Differentiability of the function is to be checked. Thanks
This video was so helpful thank you!
U r explain graphically it is very helpful sir
why in the left handed aproach f(a+h) is ((x+h)^2+4) instead of ((x^2+4)+h)?
Bcs we take x=x+h
@@dushyantdewangan294Still didn't understood. Please elaborate.
Sir for left hand derivative shouldn’t we take f(a-h)in place of f(a+h)
yes for left hand derivative
lim h->0 f(a-h)-f(a)/--h
sir can we do by differentiating both the functions and putting the point where we have to check differentiability
This was very helpful, thanks
Thank you so much!!!!!
Dhanyavad sirji
thank yuh so mch sir ❤️❤️

Chomu graph dikhai nhi deta kya,ki abh tujhe continuity bhi prove kre
No comments 🤏
Completely wrong

Yes it's wrong man , tomorrow is my exam and I completely messed up by seeing this
Brother i understand what u want to say ..... This method is not in your book or its long we use this mostly when x=0

या तो स्क्रीन पर लिख लो या बोल लो , दोनों में से एक काम कर लो तो बहेतर होगा।
क्योंकि हम लोग हिंदी जानते है
Hindi bolne chod do kya e karna bol ke ja ab english hai
I have many videos in Hindi. Here is one for you: ua-cam.com/video/uNmWFJniK6Y/v-deo.html
By the way, I live in Canada!
Sir , Kuch to Hindi bolo because all types students are here for teach mathematics 😊
To "learn"
English is universal language for all not Hindi.
