Cramer's Rule gives an explicit formulation for the unique solution to a system of \(n\) equations in \(n\) unknowns when the coefficient matrix of the system is invertible. The...
The authors discuss the evaluation of certain improper integrals by first transforming them.
The Golden Mean is found in electric circuit theory.
The author provides a short proof of Cramer’s rule that avoids using the adjoint of a matrix.
