This lesson teaches elementary functions in a practical and current way. This project was designed by The Landmark Project, and continues to be supported by the Global SchoolNet Foundation. For over 350 years, some of the greatest minds of science struggled to prove what was known as Fermat's Last Theorem - the idea that a certain simple equation had no solutions. Now hear from the man who spent seven years of his life cracking the problem, read the intriguing story of an 18th-century woman mathematician who hid her identity in order to work on Fermat's Last Theorem, and demonstrate that a related equation, the Pythagorean Theorem, is true. Cynthia Lanius makes a connection between fractals and Pascal's triangle.
