sorry if this is in the wrong section but i am doing a math problem which says f(x)=cosx and g(x)=secx for x ? ] pi/2, pi/2 [ what are these reverse brackets? edit : i am having problem with this problem. Let R be the region enclosed by the two graphs. the Region r is rotated through 2pi about the x axis to generate a solid. a) write down an integral which represents the volume of this solid. b) hence find the exact value of the volume. i have tried to find the integral using the cylinder method, but i am having trouble. i have done integral of sec(x)*cos(x)*2*(2pix) although this is a dy problem and now i am stuck
