(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Parametrize a surface obtained by revolving the curve y = lnx, as x goes from 1 to 10 about the y axis

3. The attempt at a solution

y=lnx

x=lnxcos(theta)

z=lnxsin(theta)

vector r(x,theta) = lnx cos(theta) i + lnx j + lnxsin(theta) k

0[tex]\leq[/tex] (theta) [tex]\leq[/tex] 2pi

1[tex]\leq[/tex] x [tex]\leq[/tex] 10

I'm not really sure how to complete, or if this is correct-any ideas would be helpful, thanks
