A cross-section of an airplane wing is shown. Measurements of the thickness of the wing, in centimeters, at 19-centimeter intervals are 6.3, 19.8, 26.9, 29.0, 27.7, 27.4, 24.2, 20.7, 15.6, 8.7, and 3.3. Use the Midpoint Rule with n = 5 to estimate the area of the wing's cross-section if a = 190. (Assume the thickness of the edges is nonzero.)

Tutorial Exercise Evaluate the indefinite integral. Jerez 42 + ex dx Step 1 We must decide what to choose for u. If u = f(x), then du = f'(x) dx, and so it is helpful to look for some expression in Jerez 42 + ex dx for which the derivative is also present. We see that 42 + ex is part of this integral, and the derivative of 42 + ex is ex et which is also present....
