I would really appreciate help with these two problems. Thanks!
1)
The region bounded by the curve y = x^(1/2) - 1, the lines x=2, x=3, and the x-axis, is rotated about the x-axis. Find the volume of the solid of revolution so formed.
Answer: [ 7/2 - 4.3^(1/2) +(8/3).2^(1.2) ] units^3
2)
I can't start this particular question because I don't know how to sketch
y = 1 / [ (1+x)^(1/2) ].
