UMR's Calculus Brains
Malcolm E. Hays 16 August 2002
The Calculus Brains are an earlier version of the current Algebra Brain, so they lack some of the features that have made the Algebra Brain so successful. However, both Calculus Brains still contain a wealth of information as well as some additional features not found in the Algebra Brain. If and when BrainTrax has sufficient resources, we may redevelop the Calculus Brain to fully implement some nifty features.
As with all our Brains, the Calculus Brain is composed of two primary features: The Brain navigation window and the content window. The active thought is located in the center of the Brain 'plex. Clicking on any other thought will activate and move it to the center of the Brain 'plex. Then the bottom window will load a different content page associated with the activated thought.
For instance, following the path Differentiation Basic Principles Rules Chain Rule will take you to a page about the Chain Rule of Differentiation, an important concept in Calculus I.
The other main feature of the Calculus Brains is the use of Flash video that gives a brief lecture on a given concept. We used actual UMR Calculus professors to do the voiceover and provide the lesson. No formulas were harmed in the making of these Flash videos. In order to view the Flash videos, you must have the Macromedia shockwave plugin available from Macromedia at
Many browsers will prompt you to install this plugin if it is not already installed. Check with your system administrator if you need assistance in installing this plugin.
There are over 600 thoughts combined in the Calculus I and II Brains. Not all thoughts contain detailed information, but most do. Also, many examples are given their own thought simply because they are long and involved. Each is written in extreme detail, with plain English explanations and numerous graphs to aid comprehension.
Although we also teach Calculus III here at UMR, demand for a Calculus III Brain has been low, so we have halted production of a third Calculus Brain.
Both the Calculus Brains assume that the user has a working knowledge of algebra and trigonometry. Fortunately for the user, we have both Algebra and Trigonometry Brains to assist the user in refreshing his or her memory on a particular concept. Calculus relies heavily on a thorough understanding of both algebra and trigonometry.
Feel free to explore both Calculus Brains at your leisure. Like the Algebra and Trigonometry Brains, they are available 24 hours a day, 7 days a week.
