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 ...

This course is a continuation of MATH.1380. Review of integration and methods. Solving systems of linear equations. Use and application of matrices including inverses, determinants, eigenvalues and ...

SIAM Journal on Applied Mathematics, Vol. 31, No. 4 (Dec., 1976), pp. 579-585 (7 pages) Necessary and sufficient conditions for existence and expressions for general Hermitian and nonnegative definite ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Solve the equation \(\frac{3s + 9}{4} = 7\). This means \(3s + 9\) has all been divided by 4. To solve the equation, inverse the operations. The opposite of dividing by 4 is multiplying by 4. Any ...

Algebra is part of maths where we use letters to represent unknown values or values that can change. Simplify algebraic terms Algebraic expressions can be simplified by gathering like terms. Like ...
