The figure to the right shows four regions bounded by the graph of y = x sin x: Ry, R2, Rg, and R4, whose areas are 1, I - 1, n + 1, and 2x - 1, respectively. Use this Area = 1 Area = * +1 y = XSinx information to evaluate the following integral. R2 1 R3 x sin x dx Ana = T - RA Area = 2w - 1 x sin x dx = (Type an exact answer, using x as needed.)
