We associate a sequence of Toeplitz matrices with the rational formal power series $T(z)$. An algorithm for solving linear equations with a Toeplitz matrix from this ...

Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...

Combination of real and imaginary parts (CRI) works well for solving complex symmetric linear systems. This paper develops a generalization of CRI method to determine the solution of Sylvester matrix ...

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 ...

Solve the equation \(5(2c - 3) = 19\). The equation contains a set of brackets. The easiest way to solve equations with brackets is to expand the brackets. \(\text{Area of a rectangle} = \text{base} ...
