Cycloid Optical Illusion Will Boggle Your Mind. Optical illusions typically prey on your mind’s ability to fill in blanks in the visual stimulus it is receiving.

Sometimes this can be so strong, your mind continues to be tricked even after it has been explained. Case in point: this video from brusspup, purveyor of mind-melting illusions. Matematicas Visuales. 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. CR Algebra Review. Prealgebra Review A review of the concepts in Prealgebra as preparation to enter Elementary Algebra (Math 380).

Elementary Algebra Review A review of the concepts in Elementary Algebra as preparation to enter Intermediate Algebra (Math 120). Intermediate Algebra Review A review of the concepts in Intermediate Algebra as preparation to enter a Transfer Level math class (Math 5, 15, 25, or 30). Important Information Procedure: Each review course is broken up into 6 modules.

Each module has 2 or 3 skills (labeled A, B, ...) to be reviewed.

### Calculus

Free Simulation and Modeling in Your Browser. Algebra Tiles. Virtual Manipulatives. Print Free Graph Paper. Dy/dan » Algebra: The Supplement. Differential Equations. Project MATHEMATICS! Mathematical Formula Tables. The following links are to the Mathematical Formula Tables produced by the Mathematics Department.

This gives the same information as the pink-covered booklet and the yellow-covered booklet available in exams. Currently the tables are available in and pdf format. These can be downloaded and/or viewed with Adobe Acrobat. You can access the individual sections or the tables as a whole. Making Math and Science Connections. Fill-It-In Outline Mathematics. Free Mathematics Resources OnLine. What about free graphing and algebra on your mobile phone?

XCalc is a free Java Applet which offers a graphing calculator for any mobile phone which runs Java (which is nearly all of them now!) Think about the possibilities for classes that do not yet have access to graphing calculators! While limited (it does not yet have a trace facility) it DOES offer 2d and 3d graphing which is quite fast and powerful.
