I have this assigment
Derive by using Taylor approximation of $f$ a formula for approximation of $f′(x_0),f′′(x_0),f′′′(x_0),f′′′′(x_0)$ with an error term of order $h^4$.
I have already done $f′(x_0)$ and $f′′(x_0)$ but I'm stuck trying to get $f'''(x)$. I've done the Taylor expansion for $f(x+h),f(x-h),f(x+2h),f(x-2h),f(x+3h),f(x-3h)$ and don't know what else to do.
Can someone give me some advice o help me to get $f'''(x)$?
PD Excuse my bad English.
What the assigment want me to get is something like
Randy Consuegra almost 6 yearsHi, thnks but I dont get exactly how to get from there to the formula I just added. Sorry for mentioned it just now.
Randy Consuegra almost 6 yearsI was able to solve it, by other methods. But the it was very useful. Thnks.
