- Опубликовано: 27 дек 2024
- This video tutorial provides Solved examples on Numerical Differentiation derivation of forward and backward difference formula explained in Hindi.
Note: Dear students, there is a calculation mistake in the difference table for del cube third value @4:40. The correct value should be 0.003. Further calculations will be changed accordingly. Thanks. I appologise for the mistake.
This video tutorial on Numerical Differentiation is most suitable for the students of BSc Maths, Engineering Mathematics, Gate, and students preparing for CSIR NET, IIT JAM, and competitive exams.

Then after changing it to 0.003 the answer will comes out to be 3.9438
@@shivangimaurya4426 no bro the actual answer is 3.9518 or 3.952 (approx) by calculator
Mujhe mam isme h smjh nhi aata tha ki h ki value kaha se lete h, but aaj apki video dekhne ke bad sab kuch clear ho gya,
Thanks so much mam
Thanks for help all students and me
From Bangladesh.l like your teaching method
Very nice explanation 🥰tnx you mam
Difference table 4th columm mistake 0.003
Why we are not taking the last one i.e(nabela 6th term) in backword one ....it goes further till 6th term !
Ma'am please suggest me which chanel is best for Real and complex analysis for bsc
What formula you use for calculating D^2
5:05 Del y2 4 value will be positive 0.001 not -0.001 because 0.005-0.004 = 0.001
mam 8:03 Del 4 value is -0.001 not zero
Mam -0.023 +0.026 0.004 kaise hua ye to 0.003 hoga n
Mam, When i solve this same question then i am getting 0.002 at last at ∆6
Yes It is true
Same I get
Because in del3y after subtracting -0.023+0.026 we get 0.003 Not 0.004 😊
mam 1.6 k liye hamne 6th wala ku nhi liya please reply mam
mam the value of 3rd in 3rd diff order is wrong correct once is 0.003
Maam in 2nd derivation how we get 11/12 Delta power 4???
While calculating derivarive on x=1.6 why didn't we consider Nabla6(∇6)
Madam - 0.023+0.026=0.003 right, but u r taken 0.004
yes brow i was thinking the same
wo equations dy/dx keee or dy2/dx2 kee ayii kahan se ?
Mam x= 1.6 why we didnt consider nabla 6
Mistake in difference table
Mam agr x ki value nhi di ho to question mai kya. Krenge
Your teaching way is awesome
Thank you mam
Thanks mam thanks ❤❤❤❤❤
Thanku so much Ma'am G
हमे , अभि अभि इसिका जरुरत था ।
आवश्यकता कि topic पढाइ
Kishun ji, I am happy to help! Thanks for your comment:):):):)
Mam.. backword me... Last value.. 0 nahi tha .. tho consider ku nahi kia.. ∇6 use ku nahi hua
you are very great . Thank you very much

Thank you so much!💞
A great congratulations for your lectures ...apke lectures really helpful h... thanks ma'am
Technical SMB, thanks for subscribing! I appreciate your comment, it means a lot to me. Please share:):):):):)
How we identify whether the problem is forward or backward difference
Mam can we take y0 according to the value of x?
Mam what if we are supposed to find the value of derivative exactly in the middle of the table
What about when derivative asked at middle point not at boundary point
-0.023+0.026=0.003 not 0.004 and thank you so much keep it up
Ma'am, the value of delta square will be 0.003
thanks a lot mam ,u teach really good 🙏🙏🙏😘

Mistaken in table form that lead to total wrong answer
Thank you madam
∆4 k baad calculation error h mam plz chek
Mam..... can you answer this x: 5 6 9 11
y: 12 13 14 16 obtain f (10) and y in terms of x''................(double diiff. Of x)........what formula should we apply on this forward or back.....or other.......... Plz help🙏🙏
Backward formula because 10 is close to 11
@@DrVineetaNegiMaths what we will do for X"......or what is that
great teacher
Glad you think so!
D^2 after 11/12 how much?
Mam del square y not ki value -0. 030 h
.... Apne galat likha h waha pe... Apne positive likh diya h
Am I right mam?
Thank you mam

Thank you madam, can you please provide on total Playlist on "Numerical differentiation" & "Numerical Integration"
Vanam, in the process of creating more videos on the topic! Thanks for your comment.
Tq mam
Mam app derevative using sterling interpolation pe vidio bano vo to bataya he nahi apne☹️
Namaste videos uploaded on integral calculus on rectification my question how to trace curve if no limit given in question of parametric equations
Ayush Minhas, find the points on x-axis and y-axis by the puting the value of 'theta =0 and pi /2' then trace the curve roughly. This way you can find the limits. Hope it would help!
a great lecture
