This equation is in the standard form of a linear equation: A x + B y = C, where A, B, and C are constants. The variable x is raised to the power of 1. The variable y is raised to the power of 1. The ...

Introduces ordinary differential equations, systems of linear equations, matrices, determinants, vector spaces, linear transformations, and systems of linear differential equations. Prereq., APPM 1360 ...

Non-linear physics is the study of systems where the output is not directly proportional to the input. Unlike linear systems, which follow simple, predictable relationships, non-linear systems exhibit ...

Grade school math students are likely familiar with teachers admonishing them not to just guess the answer to a problem. But a new proof establishes that, in fact, the right kind of guessing is ...

We are interested in sparse solutions of underdetermined systems of nonlinear equations and present an iterative method that updates the current iterate by a sparse vector defined as the solution of a ...

The questions in this quiz are suitable for GCSE maths students studying equations and identities, number machines, solving equations, solving equations with brackets, solving equations with unknowns ...
