I don't get this,...
Use upper&lower sums to approx. the area of the region using the indicated number of subintervals(of equal length)
It starts at 1 and ends at 2.. There are 5 squares..
What am I suppose to do?? Submation? I ended up getting lost.. Before I started it I got 1/(5+i) and had no idea how to use the submation.. Help!!
