Economist Glen Weyl says that he has a better idea: bolstering democracy with a few well-placed quadratic equations. Steven Levitt, of “Freakonomics” fame, calls Dr. Weyl’s proposal “so ...

“We had to control how big a number shows up as we do this guessing and coordination,” said Peng. Peng and Vempala prove that their algorithm can solve any sparse linear system in n 2.332 steps. This ...

In this excerpt from her new book "Vector: A Surprising Story of Space, Time, and Mathematical Transformation", mathematician Robyn Arianrhod explores the 4,000-year evolution of the language of ...

Check all formulas from CBSE Class 10 Maths Chapter 3 for revision at the time of examination. You will also get to read all necessary definition and properties related to the system of polynomials.

So f = 1, making c = 5. If a = 4, then e = 7. Our solution is {4, 5, 7, 1}. Why is this system so hard to solve by traditional algebra? It's because these aren't simple linear equations.

Quantum information researchers have tried to use linear equations as a key to unlock nonlinear differential ones for over a decade. One breakthrough came in 2010, when Dominic Berry , now at ...

Before students are presented with the quadratic formula, they’re taught a simpler method to solve certain equations. For simplicity, we’ll consider an equation where a = 1. x ² – 4 x – 5 = 0 ...
