Simple Calculus Demo	Calculus	This demonstration illustrates the relationship between a derivative function and the area below a function.	View
Standing Wave in a Tube	Physics	Standing wave in open tube. Air molecules are described as dots.	View
Three Overlapping Similar Triangles	Geometry	Two right triangles are similar if the corresponding sides are proportional to each other, and the corresponding angles are congruent. In this case, all three nested triangles are similar.	View
Tranforming Triangles Using Matrices	Matrices	Transformation matrices are used extensively in computer graphics. Learn how a transformation matrix affects a polygon by adjusting values in the matrix. See what happens when you perform a transformation with an identity matrix. Drag the blue and red points to affect the transformation matrix.	View
Transforming Sinusoidal Functions	Trigonometry	Graph may be used to understand how sinusodial functions are transformed.	View
Trapezoid Median	Geometry	The median of a trapezoid is parallel to each base and the length of the median equals one-half the sum of the lengths of the two bases.	View
Twelve Functions	Functions	Visually describes twelve different types of functions: linear, absolute value linear, quadratic, exponential, rational, radical, logarithmic, sinusoidal, third degree polynomial, step, logistic.	View
Vectors on a Slope	Physics	Describes forces on a frictionless slope. Includes position-time function.	View
Visualizing e	Number Theory	Chart and graph help to understand the relationship between e and a rational function.	View
Whisker and Box Plot	Statistics	A whisker and box plot or boxplot is a method for describing groups of numerical data through their quartiles. Box plots may also have lines extending from the boxes indicating variability outside the upper and lower quartiles.	View
