Work through the following steps to evaluate (22 + 4) dx. a ) We know that a = 1 - and b = 6 of b ) Using n subintervals, Ax = 10/ 8 c) Assume that the sample points in each interval are right endpoints. Find the following sample points: C1= 1+ 1+ 10 C3 - 1+ In general, the ith sample point is di = 1+ 5 V C Note: your answer will be an expression in terms of i and n. d) Now find the sum of the areas of n approximationg rectangles. Note: your answer will be an expression in terms of n. i= 1 (1 + 2 ) ( 2 + 2) + 50 (1 + 7) e) Finally, find the exact value of the integral by letting the number of rectangles approach infinity. (x2 + 4) dx = lim >f(x.)Ax = 91.7 ~ of i =1
