Thanks Mark,
But I have to ask you how to remove a thread that I posted just today. To this very question I got another reply saying that my answer was correct and I should put it on thread. I did that. Since the answer was wrong, I would like to withdraw it so that others who read it are...
Thanks for your suggestion.
Intersections are (0,0), (1,1) and (2,0)
And my working of this question is as follows:
a) Volume when the region is rotated about x-axis:
Method used: shell method
V=2∏∫[c-d] y g(y) dy
V=2∏{∫[0-1] y (y) dy - ∫[1-2] y(2-y^2)} dy
V=2∏{∫[0-1] y^2 dy -...
How do I set up the integral for the curve y = x, x = 2 - y^2, and y = 0 to find the volume
when it is revolved
around x axis
around y axis
about the line x = -1
y = 1
I am quite confused. Do I change x = 2 - y^2 to y = Squareroot (2 - x), when required. If I do so, does the limit...
