FE Review - Surveying - Area Computations Using Trapezoidal Rule and Simpson's

[@This_is_Dre]

really needed to know how these two work since I was absent at the time that this topic was discussed. Thanks a lot for a complete and detailed way to solve it.

I am glad it helped you!

Great explanation but kinda confused whether it should be even or odd intervals for simpsons rule. My reference manual says it has to be even.Could you clarify this

[@NathanielGuarteOgario]

same, my source also says odd num of offsets. but this vid and chatgpt say it should be odd num of intervals

[@NathanielGuarteOgario]

okay, now chatgpt says it should actually be odd number of offsets

[@MtEverest_Hotspur]

@@NathanielGuarteOgario Actually I got a clear answer on this. There're two different things we think similar but actually different here: one is intervals, other is no of data points. Pay attention to whether they are referring based off of no of intervals or no of data points. For n no of data points, there's n-1 intervals. Hope this is helpful

[@NathanielGuarteOgario]

@@MtEverest_Hotspur oh yes, what i meant about offsets are the data points. so i also meant that my reference manual says the number of intervals should be even, like yours.. i'm sorry if I caused some confusion. my reference manual uses the term offsets that's why i used that term

[@NathanielGuarteOgario]

@@MtEverest_Hotspur btw do you still use even intervals?

@@MaxAllocaTed Thank you 😊!

[@MR.Motivation_123]

really thorough explanation

[@femadeeasy]

Thanks, glad you liked it

Really good explanation , thank you
But which method is more accurate ?

[@NathanielGuarteOgario]

simpson's, since it takes the curve into consideration.
