Answer each question 1 a. (4 pts) Sketch the graph y = sin(z) over the interval (0. #] twice, Let R denote the region bound by this graph and the r-axis. Use your first sketch to illustrate how R is approximated when we use a midpoint Riemann sum with two subintervals. Use the second sketch to illustrate how R is approximated when we use the trapezoid rule sum with two subintervals. Label each graph with a detailed caption. 1 b. (4 pts) Compute the midpoint Riemann sum and trapezoid rule sum that you illustrated in 1 a. Let AM denote the value of the midpoint Riemann sum and AT denote the value of the trapezoid rule sum
