In Exercises 5 and 6, sketch the region between y sinx and y= y = cos x over the interval and find its area. G 5. In Exercises 7 and 8, let f(x) = 20-x-x and g(x)=x-5x. 7. Sketch the region enclosed by the graphs of f and g and compute its 6. [0,] Sketch the region between the graphs of f and g over [4,8], and com- pute its area as a sum of two integrals. 9. Find the area between y = e* and y = e* over [0, 1]. 10. Find the area of the region bounded by y = e* and y = 12 - e* and the y-axis. 11. Sketch the region bounded by the line y = 2 and the graph of y = sec x for - < x < and find its area. 12. Sketch the region bounded by y = 4-x and and y = -4-x for-2x2. Give a definite integral for the area of the region, but do not compute the integral. Instead, find the area using geometry.
