Direction fields and SAGE: In this
supplementary set of notes we discuss the notion of a direction (or slope) field of a differential equation. SAGE is a free opensource mathematics software system. It is easy to plot direction (slope) fields of a differential equation using SAGE. This set of notes summarizes the details of the solutions of interesting models for the Life Sciences (the exponential and logistic growth models; the LotkaVolterra predatorprey model; the Von Bertalanffy individual growth model and the Solow economic growth model). This YouTube video How Wolves Change Rivers is a good motivation to introduce the LotkaVolterra predatorprey model. This is a 2014 followup article on the New York Times: Is the Wolf a Real American Hero?

Fibonacci's numbers,
a population model, and powers of matrices: The goal of these notes is to illustrate an application of large powers of matrices. Our primary tools are the eigenvalues and eigenvectors of the matrix. We illustrate this with two familiar examples. 
Suppl. 
The online assignment for the supplement on curve fitting  least squares
approximation is due on Thursday, March 30, 11pm 

There is no handwritten homework set for the supplement on curve fitting 
least squares approximation 

Curve fitting  least squares approximation:
These notes explain how to find the "best" possible solution to a system of linear equations that has too many equations with respect to the number of variables. This is a typical issue in the Life Sciences.
