The family of graphs of x^n + y^n =1 (for even n) includes the
circle. Why do the graphs look more and more square as n increases?
In this article we shall consider how to solve problems such as
"Find all integers that leave a remainder of 1 when divided by 2,
3, and 5."
Draw graphs of the sine and modulus functions and explain the
Play a more cerebral countdown using complex numbers.
This function involves absolute values. To find the slope on the
slide use different equations to define the function in different
parts of its domain.
