Unformatted text preview: Mike Truong WeBWorK @ Dept of Mathematics and Statistics @ SDSU WeBWorK problems. WeBWorK assignment 09IntegralsVolumeRcg due 03/07/2008 at 09:00am PST. 1. (1 pt) Consider the blue vertical line shown above (click on graph for better view) connecting the graphs y = g ( x ) = sin ( 1 x ) and y = f ( x ) = cos ( 2 x ) . Referring to this blue line, match the statements below about rotating this line with the corresponding statements about the result obtained. 1. The result of rotating the line about the xaxis is 2. The result of rotating the line about the yaxis is 3. The result of rotating the line about the line y = 1 is 4. The result of rotating the line about the line x = 2 is 5. The result of rotating the line about the line x = π is 6. The result of rotating the line about the line y = 2 is 7. The result of rotating the line about the line y = π 8. The result of rotating the line about the line y = π A. a cylinder of radius π x and height cos ( 2 x ) sin ( 1 x ) B. an annulus with inner radius 2 + sin ( 1 x ) and outer ra dius 2 + cos ( 2 x ) C. an annulus with inner radius π + sin ( 1 x ) and outer ra dius π + cos ( 2 x ) D. an annulus with inner radiusD....
