Mathematics difficulties

    Use Maple to solve the problem. Solve the definite integral in each of the following ways: (1) approximately with 3 rectangles – your choice of method, (2) approximately with 10 rectangles – using the same method as your previous approximation, (3) exactly-having Maple evaluate the definite integral, and (4) exactly by geometry. For (1) and (2) include graphs of the curve with the rectangles along with a verbal explanation/descriiption. For (4) include a relevant graph of the function and a verbal explanation of your solution.
