Which concrete problem are you calculating?

im calculating for x^2+1 interval (0,3) with four rectangles for the left sum i got 8.906 but my calculator says its zero which is wrong

hi nath,what Rieman sum you are working on?

Here you go: http://www.math.psu.edu/dlittle/java/calculus/area.html Enter any function you like, find the left, right, and center sums. You can specify how many subintervals you'd like and it graphs it all. BEAUTIFUL applet. :)

ty but i want yto do it on my own calculator so i can check my answer
anonymous

did you add you L+R?
anonymous
  • anonymous
where should i add it
anonymous
  • anonymous
on you calculation in the paper you calculated
anonymous
  • anonymous
my calculation is right bc i checked my answer with the back of the book. there something wrong with my calculator
anonymous
  • anonymous
approx A= (LHS+RHS)/2
anonymous
  • anonymous
oh ok..what is the answer from the book?
anonymous
  • anonymous
what is you LHS and the RHS? so that i can relate with my calculator also, im using a casio scintific calc
anonymous
  • anonymous
mine is a graphing calcultor my left is 8.906 i didnt calculate my right
anonymous
  • anonymous
calculate also your RHS
anonymous
  • anonymous
my calculator directly computes for total Rieman sum, my calculator doesnt have a LEFT AND RIght sum
anonymous
  • anonymous
ok nath i got the solution for you calculator now,,are you there
anonymous
  • anonymous
use you calculator compute your delta x=(3-0)/4= .75. then on your calculator use the LHS Rieman sum= sigma (from 0 to 3)( (.75x)^2 +1) =11.875*.75=8.90625

i will leave for you to solve for the RHS .......hope you get the idea nath
