One of my Favorite Mac Apps is Grapher. It lets you graph everything from simple 2D equations to complex 3D equations. For example, want to see all of the Axes of symmetry for a cube? Just enter the equations x=0, y=0, z=0, x=y, x=-y, x=z, x=-z, y=z, and y=-z, and voila! Pictures make math fun! You can also save these in .gcx files. Download my cube: CubeAxesOfSymmetry.gcx
