1 Let I 2f 5:3 d3. Calculate the value of I using the following techniques: 1 a} Interpreting I as an area. b] A Riemann sum. rn + 1)2 11. Do not integrate. You may find the identityr Z k3 = useful. 11:] Let f be the following function. Note that the pieces of fare a quarter circler a line. part of parabola. and another line respectively. 10 a) Approximate / at) d1}: using a Riemann sum with 5 rectangles. Choose the sample points (righthand. left {1 hanclr or midpoint} that you believe will give the most accurate approximation. b) Explain whv these sample points are the most accurate choice. [Your answer should not refer to a calculation of the exact area]
