Draw the graph of y = sin (1/x)
for |x| < 1.
Color blue the regions inside the graph
where y is positive, and red those where it is negative.
Draw and fill the curve x4 + y4 = 1.
Then do this by relying
on a method that will draw |x|n + |y|n = 1
for any positive integer n. What happens as n goes to infinity?
