    Convergence of Unique Fourier Series

    Hi, I'm new to this forum, so I apologize if my LaTeX looks messed up. 1. Find the Fourier Series for f(x) = \sqrt{|x|} and prove it converges to f(x) 3. So, I've thus far proved that \sqrt{|x|} is piecewise continuous by proving that the limit as x approaches 0 (from both the right and...
