Differentiability at a point for a piecewise function AP Calculus

[@surendrakverma555]

Very good. Thanks 👍

[@brsmovies3368]

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

[@MathematicsTutor]

If h is very-very small it approaches zero. Thanks

[@manvitkrishna1229]

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

Great

[@yasso99991]

life saver, thank you mister Kumar!

[@vinuthasn1677]

U r explain graphically it is very helpful sir

[@yogeshr5754]

Sir ,Should we check differentiability for a derivative or for a function?

[@yogeshr5754]

Should we check it for a derivative of a function??

[@MathematicsTutor]

@@yogeshr5754 Differentiability of the function is to be checked. Thanks

[@lewisteya8195]

all I can comment is..... may lord bless you you have assisted more students

[@MathematicsTutor]

Thanks. Best Wishes to you also!

[@JackLetzelter]

This was very helpful, thanks

[@nicofe3632]

why in the left handed aproach f(a+h) is ((x+h)^2+4) instead of ((x^2+4)+h)?

[@dushyantdewangan294]

Bcs we take x=x+h

[@amkai2928]

​@@dushyantdewangan294Still didn't understood. Please elaborate.

[@TheHypercuts]

sir can we do by differentiating both the functions and putting the point where we have to check differentiability

[@JenniferTevi]

This video was so helpful thank you!

[@saihavish6460]

Sir for left hand derivative shouldn’t we take f(a-h)in place of f(a+h)

[@roshangeorge97]

yes for left hand derivative lim h->0 f(a-h)-f(a)/--h

Dhanyavad sirji

[@thierazchowdhary4736]

thank yuh so mch sir ❤️❤️

[@mohdhassan2677]

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.

[@abcd4872]

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

[@phistryingstuff8352]

Thank you so much!!!!!

Yes it's wrong man , tomorrow is my exam and I completely messed up by seeing this

[@manvitkrishna1229]

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

I have many videos in Hindi. Here is one for you: kzbin.info/www/bejne/q3_QiHmAo85-bLs By the way, I live in Canada!

[@SKGamer-nh1my]

Sir , Kuch to Hindi bolo because all types students are here for teach mathematics 😊

[@Lily-e8r1m]

To "learn"

[@rootcat643]

English is universal language for all not Hindi.

[@iteachyou4977]

​@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...
