I successfully did a problem like this before but I am stuck on this one.

Here is the question:

Find the area of the surface obtained by rotating the curve from http://gauss.vaniercollege.qc.ca/web...c67fef88e1.png to http://gauss.vaniercollege.qc.ca/web...286ca42401.png about the http://gauss.vaniercollege.qc.ca/web...22b824af51.png-axis.

Any help would be greatly appreciated!

Thanks in advance!
