Numerical Differentiation | Forward, Backward and Central Difference | Numerical Computation

In backward difference, there is a slight mistake. That is.
It should be f(2.9) instead of f(3.1).
Everything else is correct!

Please check the backward difference.
If the formula is [f(a)-f(a-h)]/h
a-h= 3-0.1=2.9
Let's take note, thank you

backward difference!!!!.you maybe mistake (3-0.1)=2.9.Thank you.

Madom hamein to Urdu bari mushkil se samjh ati ha ap English m Bta rhi hain😮😢

[brianotienootieno]

Great...you only didn't check the backward difference well

[hasanjaved]

AOA mam u made a small mistake in backward difference ..
i-e f(3-0.1)= f(2.9)=>> thats the correction

[farazsshaikh]

u did a mistake in backward difference but it is okay we understood, thanks

فيه خطأ بسيط a-h =2, 9 وشكراً على الشرح الجميل 🌹

Backward difference is wrong ma'am but thank u for the explanation
