Quadratic equations are polynomials that include an x², and teachers use them to teach students to find two solutions at once. The easier process, developed by Dr. Po-Shen Loh at Carnegie Mellon ...

We present a new method for solving the wave equation implicitly in one spatial dimension. Our approach is to discretize the wave equation in time, following the method of lines transpose, sometimes ...

A mathematician at Carnegie Mellon University has developed an easier way to solve quadratic equations. The mathematician hopes this method will help students avoid memorizing obtuse formulas.
