My 'Downloadable Articles' Homepage at http://dynamicmathematicslearning.com/homepage4.html has been updated with the following new items: 1) "What is the function?" Models the height of water being poured into a tilted container in a video clip with a simple differential equation to find the function. 2) "Relations between the sides and diagonals of a set of hexagons" Explores the analogous case for parallelohexagons of the parallelogram theorem that the sum of the squares of the sides of a parallelogram is equal to the sum of the squares of its diagonals. 3) June '13 Math eNewsletter with info about new books, website, conferences, etc. At: http://frink.machighway.com/~dynamicm/newsletter.html 4) mathematical/mathematics education quote 5) mathematics/science cartoon. My 'Dynamic Geometry Sketches' site available at: http://dynamicmathematicslearning.com/JavaGSPLinks.htm has been updated with the following: 1) A generalization of a parallelogram theorem to parallelohexagons, and Douglas' theorem for polygons. (New) 2) Hierarchical Quadrilateral Tree. (Updated) 3) Van Aubel's theorem and some generalization. (Updated) 4) Some unproved conjectures. (Updated) and the 'Student Explorations' section at: http://dynamicmathematicslearning.com/studentexplore.html with: 1) A generalization of a parallelogram theorem to parallelohexagons (New) 2) What function? Modeling the height of water against time in a tilted container (New)
