Hello, i've been in calc II for awhile and for some reason I cannot grasp the concept of what is ment by the ith subinterval. I know it has to do with summing up n number of slices. Can anyone please elaborate? Maybe have a simple explanation for what the ith subinterval is ? Thanks(adsbygoogle = window.adsbygoogle || []).push({});
