Volume and symmetry

dimanche 1 septembre 2013

1. The problem statement, all variables and given/known data



Your supposed to set up the integral and do it from the calculator.

y = , y = (cosx)^2, -pi/2 <= x <= pi/2

a. x axis

b. y axis

2. Relevant equations





I = ∏∫(cosx)^4 dx = 3.70110 and for part b

I = ∏∫((1)-(cosx)^2)^2 dx = 3.70110



3. The attempt at a solution



Did I set this up right? It would be the same volume in both cases right?
