Actually @Math4life, sorry that doesn't apply here. Actually you can calcluate the area with sum of areas of rectangles of 0.5 wide. See below(part 1) dw:1337244533262:dw For part a), the base of each rectangle is 0.5, and the height is f(k), for k = {0.5, 1, 1.5, 2}. Therefore the area is about .5(f(.5) + f(1) + f(1.5) + f(2)) = 10.75.

@Math4Life , now look and compare both the graphs(part a and part b), you will find the difference Part A) dw:1337245054089:dw Part B) dw:1337245178974:dw
