Welcome to my homepage!
I am not teaching in Summer 2020, and I am on sabbatical leave Fall 2020 and Winter 2021. I will be working on openly licensed software and educational resources. Through all of that time, I’ll still be assisting faculty as needed with use of our OER course materials and WeBWorK. And I will be available to anyone via email.
The following is to demonstrate to other PCC faculty how it is possible to include mathematics in our staff websites.
In precollege courses, we learn that \(\frac{1}{2}+\frac{2}{3}=\frac{7}{6}\), that \(\sqrt{81}=9\), and the meaning of \(A=\pi r^2\). We also learn how to solve equations like \(2x+1=7\), \(x^2+13x+4=0\), \(\sqrt{x+1}=x-1\), and \(\frac{x}{x+2}+\frac{2x}{x-2}=12\).
In 200-level math courses, we might see things like:
\[\int_0^1e^x\,dx=e-1\]
\[\sum_{n=1}^{\infty}\frac{1}{n^2}=\frac{\pi^2}{6}\]
\[\begin{bmatrix}1&2&3\\4&5&6\\7&8&9\end{bmatrix}\vec{x}=\vec{0}\]
