In the circle below, the sum of which arcs is equivalent to arc AE? 1. arc AE = arc AB + arc BC
2. arc AE = arc AC + arc CD
3. arc AE = arc AD + arc DE
4. arc AE = arc CD + arc DE

What is the quadric regression equation that fits these data

Determine whether the following statements are true and give an explanation or counterexample. bold a. when using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. bold b. if a region is revolved about the y-axis, then the shell method must be used. bold c. if a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y.

Write the summation to estimate the area under the curve y = 1 + x2 from x = -1 to x = 2 using 3 rectangles and right endpoints
