2. Set up (don't evaluate) the following volume integrals, for the region bounded by the given curves and revolved about the given line. Be sure to use only the disc/washer method for these. (a) region: above the x-axis, bounded by (b) region: bounded by v=x , x=1 , x=2 x 2 + 1 =1 ; revolved about the x-axis and y= x ; revolved about the x-axis. (c) region: bounded by y=v2+x- , the x-axis, (d) region: bounded by y=vx , x=0 , y=1 ; x=1 and x=2 ; revolved about the line revolved about the y-axis y =-1. (e) region: bounded by y=vx , x=0 , y=1 ; (f) region: bounded by y=vx , x=0 , y=1 ; revolved about the line x = 5 revolved about the line x = -5
