What is a matrix in Mathematics? — Definition and Examples

Intro­duc­tion In this arti­cle we talk about matri­ces in math­e­mat­ics, how they are defined, what types of matri­ces there are and we are going to see some exam­ples. A matrix is an ordered array of num­bers, con­sist­ing of a series of rows and columns, such that each ele­ment occu­pies a posi­tion and can be identified …

Factorial Function

Intro­duc­tion In this arti­cle we will see how to define the fac­to­r­i­al oper­a­tion of a num­ber, cal­cu­la­tions and prop­er­ties. It is a use­ful oper­a­tion that is com­mon­ly applied in the devel­op­ment in series of func­tions. Def­i­n­i­tion of the Fac­to­r­i­al Func­tion This oper­a­tion is sym­bol­ized with the admi­ra­tion sym­bol in front of the num­ber to apply …

Summation and Product Notation

Intro­duc­tion In this arti­cle we are going to talk about the sum­ma­tion and prod­uct nota­tion, what they mean and how to per­form the cal­cu­la­tions. At the end we will see how to pro­gram sum­ma­tion and prod­uct nota­tion in Java or C# lan­guage. What is sum­ma­tion and prod­uct nota­tion? Sum­ma­tion and prod­uct are ways of defining …

Cartesian Plane — Coordinate System

Intro­duc­tion The Carte­sian coor­di­nate sys­tem is named after the philoso­pher and math­e­mati­cian René Descartes, con­sid­ered the cre­ator of ana­lyt­i­cal geom­e­try. This sys­tem allows us to rep­re­sent points on a line, in the plane and in space using arrays of num­bers. For exam­ple: (1,5), (-3,0), (4,1,-1), etc. What is a Carte­sian plane? The Carte­sian plane is …

Numerical sets. Types of numbers and application

Intro­duc­tion Numer­ic sets are used to group num­bers that have sim­i­lar char­ac­ter­is­tics. It is one of the basic con­cepts of math­e­mat­ics so it is impor­tant to under­stand what they are and what char­ac­ter­is­tics each has. What are num­ber sets used for? Numer­ic sets are used to sep­a­rate num­bers into dif­fer­ent class­es that have sim­i­lar prop­er­ties.  We must …

Vector — Mathematics

Intro­duc­tion A vec­tor is a math­e­mat­i­cal tool that allows us to rep­re­sent mag­ni­tudes in which not only the inten­si­ty (or mod­u­lus), but also the direc­tion and direc­tion in which they are applied are impor­tant.  The vec­tors are very use­ful in the devel­op­ment of games, they allow us to define direc­tions for move­ment, do ray tracing, …
