Sketch each region contained by the boundaries below. Decide if you should use horizontal or vertical rectangles to calculate each area. Then, set up and evaluate an integral to calculate the area. Check your solution with your calculator. Homework Help ✎
, , , and
Regarding horizontal or vertical rectangles... Is there a top function and a bottom function?
Or, is there a left-most function and a right-most function?
If it's the former, use vertical rectangles (and keep the equations written in
If it's the later, use horizontal rectangles (and keep the equations written as
__________________ form). and
Regarding the graph of
In order to visualize this graph, you should not have to rewrite the equation in
You should know that it will look like a sleeping (sideways) parabola with vertex at
The negative indicates that the parabola opens to the left.
Might as well be consistent and write the first function as
______________ as well.
Regarding horizontal or vertical rectangles...
Refer to the hint in part (a).
