## Math for Everyone explores Newton's method

### February 26, 2015 • Categories: Announcements and Department Events

This past Thursday (Feb. 19) at the Math for Everyone lecture series, Jeffrey Diller, professor of mathematics at the University of Notre Dame, gave a presentation about imaginary numbers, unsolvable equations, and Newton’s method.

Diller opened his presentation by posing the question of what mathematicians do, one of which is to solve equations. He then delved into equations that are unsolvable, like non-linear equations. “When we can’t solve equations, we need methods to approximate solutions to equations,” said Diller.
