Thread: Integrals

The table gives the values of a function obtained from an experiment. Use the values to estimate using six equal subintervals with left endpoints. x 0 1 2 3 4 5 6 9.7 8.9 8.4 6.1 4.5 -6.9 -10.3

I got 50.3, but it's wrong.

sorry, the data didn't show. here it is:

Use the values to estimate integral from 0 to 6 using six equal subintervals with left endpoints.

(0, 9.7) (1, 8.9) (2, 8.4) (3, 6.1) (4, 4.5) (5, -6.9) (6, -10.3)
