: Concerns the extension of bounded linear functionals. geometry returns: angles

When the norm comes from an inner product, we enter the elegant world of Hilbert spaces. Here, geometry returns: angles, orthogonality, and projections work much like in ℝⁿ, but in infinite dimensions. The Fourier series, for instance, is simply an expansion in an orthonormal basis of L²[−π, π]. geometry returns: angles
