The volume below the surface z=sin(x)cos(y), above the xy-plane and inside the rectangle [0,pi/2]x[0,pi/2] is approximated by 8 slices, where the y-value has been held constant at the midpoint of each sub-interval (so y=pi/32, 3pi/32, ... , 15pi/32). This is an illustration of Fubini's Theorem and iterated integration.
This model pairs nicely with Volume: slices x constant and Volume: no slices. See http://www.thingiverse.com/thing:928461 and http://www.thingiverse.com/thing:928456.
This model was designed and printed by my WLU summer research student Ryan McDonnell ('17).
This object was made on a MakerBot2X. We used the following settings:
0.20mm layer height
10% infill (hexagonal pattern)
