Calkin-Wilf-Newman function.... or something 1. The problem statement, all variables and given/known data I have no idea what this has to do with our current chapter in Calc II but it seems simple enough. [PLAIN]http://img253.imageshack.us/img253/2192/mathv.png [Broken] 2. Relevant equations 3. The attempt at a solution I managed fine for the first two, but I have no idea what to do for pi. The only way I can think to express pi as a rational plus a number is 3 + (pi - 3). Evaluating their function for that A and B can't give me an "exact answer" which is what they ask for.
