Best ResponseYou've already chosen the best response.1Hi, if you divide the interval into 4 subintervals each sub interval is of length one. Now the value of the function at 1,2,3,4,5 are 6,3,2,3/2,6/5. For example for the trapezoid on top of the first interval, the area is (6+3)/2 * 1 = 9/2. Do the same thing for the other sub intervals and add them all at the end to approximate the integral.
