Examine the 2P orbitals in Mathematica through the Mathematica demonstrations. How is the 3D shape of the P-orbitals altered when the radial distribution probability as opposed to the Spherical Harmonic alone? Wolfram Alpha provides information and 2D representations of the Spherical Harmonics to also aid in examination using SphericalHarmonicY (1,1, theta, phi).
