simpsons rule question - the displacement? (1 Viewer)

[mdunn94]

I cant remember exactly but my answer was approx 1500? i dunno if it was right but
what did you get

I'm hoping for 105-112
​

I think I got around 2000 something. lol


It was a mixed fraction btw.

 

[weirdguy99]

I think I got 2800..or 2600 (?)... just do the question again.

 

[Awkward_Ninja]

Did anyone separate it into 2 separate integrals?
I think i got like 1900 or something.

 

[mdunn94]

what about the question how it was like how much does L increase when I is doubled, I got ln 2? i think it might be 10 ln 2

That question was easy as crap. There were no tricks to it at all. Literally just needed to know the formula u idiot!

you are wrong

I like how there are 4 different answers from 4 different people.

Can someone please upload the question/paper?

you are wrong

your name is matthew goodwin...everyone neg rep him

the answer is "x"

Something like this..

h=20-0/4 = 5

d=(5/3){(173+168)+2(127)+4(81+195)}
=2831.67

 

[friend177]

Got around 2832 somein like that

 

[friend177]

Something like this..

h=20-0/4 = 5

d=(5/3){(173+168)+2(127)+4(81+195)}
=2831.67

Correct

That's the ticket!!

with this question, were you supposed to figure out the distance traveled for each interval doing d=v/t? then plug each value into simpsons?

I don't think so..you can just do the (h/3){(add end values) + 2(odd) + 4(even)} and that will give you the right answer.

I did something like this:
Distance = (5/3)*(173+(4*81)+127) + (5/3)*(127+(4*195)+168)
= (5/3)*(1699)
I think i may have had an addition error with the second one.
=(6895/3)
= 2298.33
Yeah, i think i screwed it up.

Hopefully separating it int

 

[weirdguy99]

I did something like this:
Distance = (5/3)*(173+(4*81)+127) + (5/3)*(127+(4*195)+168)
= (5/3)*(1699)

You got (5/3)x1699 CORRECTTTTT.
You just made a calculation error..
