Euler's Formula in College Algebra

Once complex numbers are introduced in a College Algebra/PreCalculus course, why not discuss Euler’s formula? Especially the equation $e^{\pi i}+1=0$, that looks good on a T-shirt. A full proof is out of question, but the power series definitions of the exponential and trigonometric functions provide a walkable path up to the summit. With a computer algebra system it is easy to demonstrate how the approximations work, just by entering a few terms of the infinite sums.

Talk on finite computational structures

Here are the slides for my talk “Finite Computational Structures and Implementations” for the The 4th International Symposium on Computing and Networking CANDAR’16 held in Hiroshima, Japan, November 22-25, 2016.

The photo was taken in the Higashi Hiroshima Arts and Culture Hall, the venue of the conference.
