T-shirt, dark: polynomials orthogonal, full back T-Shirt

It's time to declare your support for orthogonal polynomials and what a better place to start than the domain of the unit disc. These beautifully rendered Zernike polynomials make it obvious that the unit disc produces the most elegant orthogonal set. The back features a table showing the first polynomials in three coordinate systems: Cartesian, polar and complex. This shirt is for you whether your interest in orthogonal representations is a curiosity, a hobby or a passion. Share your love of mathematics and your refined sense of fashion with those around you and help to broaden perspectives at the same time.
