Course Communities

So far, we have identified resources for one-variable calculus, multivariable calculus, a first course in ordinary differential equations, and a probability course, as well as for a pseudocourse containing resources for developmental mathematics.

This collection of thirty Geogebra applets has been upgraded to use HTML 5, so they will run on tablets. The applets cover limits, differentiation, applications of the derivative, and the integral. The style is clean and focuses on the ideas that the author wants to emphasize.

The applet is written in HTML5, so it is available on tablets. The object is to identify which of three possible graphs represents the derivative of a function given by a graph. There are a seemingly infinite number of different functions available.

The applet is written in HTML5, so it is available on tablets. It has a clean look and feel with nine examples. There are exploration questions and an idea for a project.

This is an interactive graphical representation of the universe of probability distributions. Users can search, explore, discover or investigate the intrinsic properties of different probability distributions and inter-distribution relations. In addition, users may utilize many of the web-based probability calculators, simulators and virtual experiments.

This resource is an article in Mathematics Magazine (2009); it also appears in Classroom Capsules and Notes. "The author proposes two extensions of the Monte Hall problem, with solutions involving the numbers \(\pi\) and \(e\), respectively."

The lesson begins with an application problem to motivate the necessity and use of a logarithm. The formal definition linking logs and exponents is then introduced. Exercises in writing exponential equations as logarithms follows before a calculator based method for approximating logarithmic values is discussed. The common log, i.e. logs of base \(10\), is introduced and a procedure for solving common log equations with a calculator is presented, along with various caveats about proper syntax for the calculator.
