Homework Statement
Find the volume of the solid generated by revolving the area bounded by
y = sec[x], y= [tex]\sqrt{2}[/tex]
- [tex]\pi[/tex]/4 [tex]\leq[/tex] x [tex]\leq[/tex] [tex]\pi[/tex]/4 about the x-axis

Homework Equations
a = lower limit = --[tex]\pi[/tex]/4
b = upper limit = [tex]\pi[/tex]/4
V = [tex]\int[/tex] a->b R2 - r2 dx
The Attempt at a Solution
V = [tex]\int[/tex] a->b R2 - r2 dx
V = [tex]\pi[/tex] [tex]\sqrt{2}[/tex]2 - [tex]\pi[/tex]*sec[x] = a->b([tex]\pi[/tex]*2x) - ([tex]\pi[/tex]*[tan[x]])a->b
Note: Ans = [tex]\pi[/tex][[tex]\pi[/tex] - 2]
