(a) Use the trapezoidal rule to find the area under the curve #y=x^2 + 1# from x=1 to x=15 using seven strips.
(b) The cross-sectional area in #m^2# along the length of an 18 m wooden log are: 5.0, 5.4, 7.0, 8.0, 5.5, 5.8, 6.0
The cross-sectional areas are equally spaced. The first and the last areas represent the ends of the log. Estimate its volume using the trapezoidal rule.
