Draw graphs of the sine and modulus functions and explain the
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."
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?
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.
Play a more cerebral countdown using complex numbers.
