Everyone learns (and some readers maybe still remember) the quadratic formula. It’s a pillar of algebra and allows you to solve equations like Ax 2 +Bx+C=0. But just because you’ve used it doesn’t ...

In this paper, we present some invariants and conservation laws of general linear methods applied to differential equation systems. We show that the quadratic invariants and symplecticity of the ...

Google is celebrating the quadratic equation with a special Doodle today, November 12. The Doodle highlights one of mathematics’ most recognised and widely applied formulas, bringing an everyday ...
