The Imaginary Number System: Is it Really Imaginary? ... Presumably one would think that this number system does not exist at all. ... Imaginary numbers make up what mathematicians call the complex number system. ... The four most common number systems that can be understood why they exist. ... That is what the Complex number system explains. ...
Computers, science, etc. all need some mathematical equation to make it possible. e has changed how society looks on banking. e has changed how we compute continuous compound interest. ... He also defined a curve, a "logarithmic" curve, but we call it the exponential curve, the equation is y=ka^x. ... Banks use the equations to figure out how much is gained be a set date or by a continuos interest rate. ... e has changed the world but not dramatically. e has helped us discover new techniques to old techniques. e has changed banking systems. e has helped with progression of not only mathemati...
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...
