It's PI, not PIE for goodness sake.
This is a question on one of my past exams that I'm trying to do...
the question says to find the volume of the regions bounded by y=x^2-2 and
rotated about x=2
I was thinking that the radius equalls (2-x) [I'm not entirely sure about this]
and the height equals (x-(x^2-2))
all of them multiplied together with PIE under the integral from -1 to 2
is this correct?
Actually, it does allow it...to a point. I have posted them before. But, with this one, I had to resize the picture. When I did, it wouldn't animate. I used to post animated graphs, but it seems lately it won't handle them unless I resize, then it doesn't work.
