Understanding the Error in Simpson's 1/8 Integration Method

[SOLVED] Simpson 1/8 Integration

How does it has an error of h^5 * f^4(c)/90
when Langrane/Newton of order 2 is used to derive this,
and you should get f^3(c) as an error?

 

[rootX]

f^3 cancel out if you go from -1 to 1
I was using t as 0 1 2

Your link doesn't work. At least not for me.

It does work for me :D
It just an online book where they have derivation for the Simpson error.

It might work for you, but that doesn't mean it will work for everybody. I get "An Error Occurred Setting Your User Cookie" using firefox in linux. It's really best to avoid links if you want everyone to be able to see the problem.

oo Thanks for pointing out.

I restarted my computer and now it neither works for me ><

Anyone, who sees a related problem.. just
see the JSTOR website: using google: "simpson's error, derivation" or JSTOR: 3268

That's a solution though
