The following sample Mathematica graphics are available in postscript format:

• Scattering in a force field, from the chapter on kinematics. The same picture is shown in gif format at the top of this page.
• A saddle surface, from the chapter on geometry of surfaces.
• A quartic surface, from the problem set on geometry of surfaces. The same picture is shown in gif format at the top of this page.
• One component of the solid region bounded by a cylinder and a torus, from the chapter on multiple integrals. The same picture is shown in gif format at the bottom right of this page.
• The elctrostatic field generated by two charged loops, from the problem set on physical applications of vector calculus.
• Fluid flow around an obstacle, from the problem set on physical applications of vector calculus.
