From the last assignment we found x cos(x) sin(x) dx = - sin(2x) - =x cos(2x) Using the result find x cos(x) sin(x) dx = Enter an exact answer, not a decimal. The answer is negative because the area below the curve is greater than the area above the curve. Find the total area of the shaded region. You will need to break the integral in to two parts, but it should be easy to find where the curve crosses the x axis. Total area =
