Unformatted text preview: 3. (4 points) Determine if the integral Z 9 1 dx (9-x ) 1 3 converges or diverges; if it converges, compute its value. 4. (4 points) The region bounded by y = sin( x ), y = 0, x = 0, and x = π is rotated about the x-axis. Find the volume of the resulting solid. 5. (4 points) Estimate Z 5 1 q √ x-1 dx using the Trapezoidal Rule with two subintervals ( n = 2). You need not simplify the resulting expression....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
