If I say truth, the formula u created on 11:00 is wrong, it will be created with differentiation, answer comes wrong while using this formula delta x/x=Delta a/a +Delta b/b + Delta(a+b)/a+b (this formula is only valid for percentage error not for absolute error) 😊 According to differentiation formula will be different and absolute error will be delta R equivalent, after which we will convert it into percentage error.... I studied and analysed very carefully before posting this comment but yeah it's right And the correct formula is :-) delta x/x²= delta a/a²+ delta b/b² Thanks for reading the comment! Have a nice day! Btw beautiful lecture!! 😊👌👌👌
Congrats🥳🎉🎉 for 7 millions subs //alakh sir... Heartily congratulations to you😚❤... Really u deserve more appreciate your hard work... Hat's off to you sir.. 🤩😇

Sir i can't express how to say thanx to you. Really Sir your explanation is amazing,very nice....really sir thank you very much for your mind blowing explanation. In first time I don't like phy but after see your video I am also become a fan of phy really sir once again thank you for all the thing

I am neet aspirant and enjoying the neet/ jee advance questions.... because of only you sir 😊
If I say truth, the formula u created on 11:00 is wrong, it will be created with differentiation, answer comes wrong while using this formula
delta x/x=Delta a/a +Delta b/b + Delta(a+b)/a+b (this formula is only valid for percentage error not for absolute error) 😊
According to differentiation formula will be different and absolute error will be delta R equivalent, after which we will convert it into percentage error....
I studied and analysed very carefully before posting this comment but yeah it's right
And the correct formula is :-)
delta x/x²= delta a/a²+ delta b/b²
Thanks for reading the comment!
Have a nice day!
Btw beautiful lecture!!
😊👌👌👌

Yes you are right
Bhai how do I say thankyou to you man really really thanks
