how are you supposed to divide 140 in to three sub intervals? got me.

It changed it to 120

i guess each has length of \(46\tfrac{2}{3}\) and you take the midpoint so first sample point would be at \(23\tfrac{1}{3}\)

you just ignore the 140 I guess

so it would be 30

no one third of 120 is 40

oh crap I thought it was four intervals

satellite73 Group TitleBest ResponseYou've already chosen the best response.1
one interval would be \([0,40]\) next would be \([40,80]\) and last would be \([80,120]\) you would sample as \(20,60,100\)

so it would be 40[ f(20)+f(60)+f(100)] ?

yes that should do it

@satellite73 but it talks about rectangles so for each interval do I just do the X*y?

It's still wrong. :(

yes it is just rectangles, base times height

is the last 140,8 gone or something?

40[(2*20)+(4*20)+(8*20)]

I don't know, but this is what I did using base times height

and it's still wrong

satellite73 Group TitleBest ResponseYou've already chosen the best response.1
oh i see what you did wrong
 2 years ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.1
the base if 40, the height is 2, 4 and 8 respectively

satellite73 Group TitleBest ResponseYou've already chosen the best response.1
you wrote \(40[ f(20)+f(60)+f(100)]\)
 2 years ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.1
that is correct, and \(f(20)=2,f(60)=4, f(100)=8\) so it should be \[40(2+4+8)\]
