Large Print macros for LaTeX

 It is somewhat tricky to produce a large print version of a LaTeX document for visually-impaired students. I have worked out a general scheme that allows me to quickly convert documents to large print.

BUGBOX Mathematical Modeling Simulations

 I have written software that can be used for inquiry-based learning of mathematical modeling for population dynamics. The software creates a virtual laboratory space inhabited by virtual insects. Students conduct experiments and devise mathematical models to predict the experiment results.

In BUGBOX_predator, students do experiments to find a relationship between prey density and consumption by one predator.

In BUGBOX_population, students observe the changes in the insect population to discover aspects of the insects' life cycle. They can construct a simple linear difference equation model, using their observations to estimate the parameter values. Four different scenarios give a sequence of increasing complexity.

Course Notes

Calculus I

Derivative Concept briefly summarizes the concept of the derivative for functions of 1 variable, with emphasis on the geometric significance of the derivative.

Calculus III

Quadric Surfaces describes the various quadric surfaces aligned along a coordinate axis.

Derivatives summarizes the different types of derivatives for scalar functions of more than one variable.

Directional Slope lays the groundwork for the development of the directional derivative by considering the slope in a given direction of a linear function. Exercises are included.

Differential Polemic is a passionate plea for mathematicians to stop co-opting the notation of the differential when doing linear approximation.

Extrema summarizes the concepts and methods of local and global extrema for functions of two variables.
