Let R be the region enclosed by the curves y=6sin2x and y=6 over the segment [ π/2,3π/2]. Find the volume of the solid that is obtained by rotating R about the line y=−1.1.
i get V=451.7359646 but its wrong..
== >
then i found the antiderivative of sin4x and sin2x and got the final answer of the Volume. what did i mess up on?
