13-18 Sketch the region enclosed by the given curves and find its area. 13. v = 12 2 6\f23. Sketch the region that lies between the curves 3.! = cos x and y = sin 2x and between it = 0 and x = 473/2. Notice that the region consists of two separate parts. Find the area of this region. 28. A cross-section of an airplane wing is shown. Measurements of the thickness of the wing, in centimeters, at 20-centimeter intervals are 5.8, 20.3, 26.7, 29.0, 27.6, 27.3, 23.8, 20.5, 15.1, 8.7, and 2.8. Use Simpson's Rule to estimate the area of the wing's cross-section. 200 cm29. If the birth rate of a population is b() = 2200e 0.024r people per year and the death rate is d(t) = 1460e 0.018 people per year, find the area between these curves for 0 E t = 10.
