Homework Statement
The curve is rotated about the y axis, find the area of the resulting surface.
y=(1/4)X2-.5ln|x| 1<_X<_2
Homework Equations
S=2(pi)(f(x))[tex]\sqrt{}1+f'(x)^2[/tex]
The Attempt at a Solution
Alright I'm not entirely sure where to even begin. Since I'm rotating about the Y-axis I know that I need to solve the limits wrt y, which would be 1/4<_y<_0.65345
Then I need to solve the equation so X is isolated, then take the derivative of that.
I'm not entirely sure where to even begin, I know that I could take everything to the e^ to get rid of the natural log of x, but then everything is to the e^.
