Portfolio Solving Systems of Equations Systems with two variables: 1. ... Systems with three variables 1. ... Systems with N variables 1. ... Solve just as if you were solving for a system of equations. 5. ... Matrices A matrix is a rectangular array of numbers used to organize information which would normally be used in a system of equations. ...
For example, in electrical engineering we find complex roots in circuit theory where the polynomial is part of the model equation for simple circuits. ... From the perspective of algebra, complex numbers give us a complete system for finding the roots of polynomials. ... They are used for approximating or curve fitting experimental data, solving different equations, calculating "beam deflection" for loading trucks, representing the properties of some gasses, defining functions used in Finite Element computation, defining CAD geometry in CAD (Computer Assisted Drawing) engineering and construct...
