Help: Logarithmic cuve area/volume (1 Viewer)

[Meldrum]

1) Find the area between the curve y=lnx, the y-axis and the lines y=2, y=3; I pretty much only need help turning it into x=

2) Find the exact volume of the solid formed when the curve y=log-e-x is rotated about between the y-axis from y=1 to y=3; same deal with the x=

Much thanks, in advance.

1) y=Inx; x = e^y, and you said you could do the rest.
2) I do not understand 'y=log-e-x'? unless you simply mean x=log-e-y?

And I should've stayed in it, instead.

I'm scared because:

1) My questions are from McGraw Hill
2) I'm starting to think that all the maths books are almost the same. The only reason that Cambridge is so good is because no one likes the POM's, and accordingly, they won't share with them, and
3) There are 3 other Bored(ers) with your userpic.

What the? Does that randomness deserve a 'sigging'?
