As intimidating as this looks, hiding inside is a simple secret that makes solving every quadratic equation easy: symmetry. Let’s look at how symmetry makes the quadratic formula work and how a lack ...

They contain, practically, an outline of three distinct methods, that of combining a deficient set of linear equations, that of partial fractions, derived from Euler's generating function, and a ...

We give a method for finding a minimal point adjacent to 1 of the reduced lattice in cubic number fields using an isotropic vector of the quadratic form and two-dimensional lattice.
