Notes on fixed points and experimental mathematics. (Notas sobre puntos fijos y matemática experimental.) (Spanish. English summary)
Bol., Soc. “Puig Adam" Profr. Mat., No. 73, 31-43 (2006).
Summary: Starting from general considerations on mathematical experiments implemented by computer, the present experimentalization of mathematics is acknowledged. Some elementary geometrical examples are exposed, and the paper concludes with a short study of results experimentally obtained examining and graphically interpreting the transcendental equations $\sin(\frac 1x)=0$ and $\sin(\frac{1} {\sqrt{x^2+y^2}})=0$.
