    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

    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. :)

    my calculator directly computes for total Rieman sum, my calculator doesnt have a LEFT AND RIght sum

    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
