In MatematicasVisuales you will find visual expositions of mathematical concepts.
MatematicasVisuales intends to complement the work initiated by artiludios, a site with games, puzzles and mathematical curiosities.
Reading Miguel de Guzmán I found a demonstration of the line of Simpson and the Steiner Deltoid. It serves as an introduction to the geometry section.
The concept of function and its graphical representation are a key concept and we dedicate special attention to it in the analysis section.
Geometric representation of the complex numbers facilitates its visualization. The representation of complex functions usually needs dimension fourth. Sometimes, this difficulty is avoided using colors with which useful and attractive representations are obtained.
Thinking in who have to start learning probability we have this section about this subject.
In the history section we approach mathematics through its history. I try to present the origin and growth of some mathematical concepts.
Miguel Cardil made the design of matematicasvisuales.com. You can see more of his works in www.mcardil.com. Do not miss his Stick Figure Museum.

Loci has published my article
Kepler:The volume of a wine barrel.
Loci is a publication of the Mathematical Asociation of America (MAA). It is the journal of the Matematical Science Digital Library
(MathDL). Thanks to Janet Beery, editor of Loci, for her help and encouragement.
They has also choosen
Taylor Polynomials - Exponential Functions
as a resource in his Course Communities in Undergraduate Mathematics.

Polynomials of degree 2 are quadratic functions. Their graphs are parabolas. The derivative of a quadric function is a linear function, it is to say, a straight line.

Two points determine a stright line. As a function we call it a linear function. We can see the slope of a line and how we can get the equation of a line through two points. The derivative of a lineal function is a constant function.
