Formula confusion (Simpson's Rule) (1 Viewer)

[BlueGas]

Which formula do I use?

Formula 1:

Formula 2: (The formula under "this reads")

First formula should be h/3 not h/2
then it's the same thing as the second one
you should take a look at youtube videos if you are confused by the different definitions/forms of the Simspon's

Most people primarily get confused by 'odd' or 'even'. You have to establish this knowledge yourself by attempting a question and checking answers.

Someone pls respond IDK either

use the original simpsons rule u posted, aka f1

I don't know what you're on about.

Yes I got confused at the start, but I think I get it. By odd, don't they mean even ordinates and odd, even ordinates?

yes, so let's take f(o),f(1),f(2),f(3).f(4)
first and last is f(0) and f(4)
we take 4x(f(1)+f(3))
then 2xf(2)

How come you don't do 2 x (f(2)+f(4))? Since you done 4 x (f(1) + f(3)).

it's the last function. look at the formula you posted

Ahh okay, got it. Thanks.

People often don't understand properly because they are just trying to remember which formulae to use, and then how to plug in the values to get the answers. They don't understand the basis for the 2 formulae, one for Trapezoidal and one for Simpson's

So I'll assume formula one is the trapezoidal rule because h is being divided by 2 and Simpsons rule is formula 2?

No! No! No! No! No!

Formula 1 is for Simpson's rule, but as pointed out to you by Kaido, it is "h/3" and not "h/2". The Trapezoidal rule has a different formula and has a "h/2" in front.
