What are your thoughts? What have you tried? Where are you getting stuck? ("Read Before Posting")

Please be complete, so that we can see where things are going sideways. Thank you!

Does this section of your book teach about using the differential to approximate values of a function? Please try to use whatever method it teaches, and show us what went wrong.

$\displaystyle f'(a) ~ \dfrac{f(a+h) - f(a)}{h}$
What is a and h?

 

[blamocur]

$\displaystyle f'(a) ~ \dfrac{f(a+h) - f(a)}{h}$
What is a and h?

Your "~" does not show up in the post. Might want to use $\sim$ ("\sim") instead.

Your "~" does not show up in the post. Might want to use ∼\sim∼ ("\sim") instead.

Also there is $\approx$ ("\approx"), whose name seems to be more fitting the context.
