This week I will post 2 problems because I am not sure how this is still going to work.

First: Given the diophantine equation,

show that the number of solutions cannot exceed . (Easy)

Second: The Dirchlet function:

Show that the Dirichlet function is not Riemann integratble on (Hard)

This Dirchlet function is defined to map rationals into zero and irrationals into one.
