University of Houston-Clear Lake’s Mathematics and Statistics Department recently acquired a 3-D printer to help students understand complex surfaces. Calculus involves three-dimensional objects that can be extremely difficult to visualize. Now the department can print 3-D surfaces, and students can see details that were previously inaccessible. Pictured is Deanna Henderson, a calculus student, observing how the volume of a half torus can be found with cylindrical shells.
