Classic Curves - the Limaçon
http://www.maplesoft.com/applications/view.aspx?SID=4872&ref=Feed
The limaçon (Pascal's limaçon) is a classic curve in geometry, known from the 16th century. This worksheet shows how to construct and plot it in a variety of ways, including animations of the construction methods. The method of trisecting the angle using a special case, the trisectrix, is described. The worksheet provides many examples of using the geometry package.<img src="/view.aspx?si=4872/Limacon_70.jpg" alt="Classic Curves - the Limaçon" align="left"/>The limaçon (Pascal's limaçon) is a classic curve in geometry, known from the 16th century.

This worksheet shows several construction methods for the Nephroid, a kidney shaped curve, as examples of using the geometry package. The nephroid can be seen as reflected light in a container of milk, as pictured and constructed here.<img src="/view.aspx?si=4874/Nephroid_59.jpg" alt="Classic Curves - the Nephroid" align="left"/>This worksheet shows several construction methods for the Nephroid, a kidney shaped curve, as examples of using the geometry package.

http://www.maplesoft.com/applications/view.aspx?SID=4865&ref=Feed
A package to manipulate and plot atomic orbitals and spherical harmonics. Hydrogenic and Slater-type orbitals are supported, as are arbitrary radial functions. Quantum mechanical integrals are included that act on these orbitals: 2-centre overlap integrals and 4-electron atomic integrals, including coulomb and exchange integrals.
Help pages and an example worksheet are included.
This is an update of a version of the orbitals package that was published in 2003.<img src="/view.aspx?si=4865/Orbitals_29.jpg" alt="Orbitals Package" align="left"/>A package to manipulate and plot atomic orbitals and spherical harmonics.
