# Splitting Infinite Series into Real and Imaginary Parts

 P: 294 I need a quick reminder that this is (hopefully) true: Let $\sum a_n$ be an infinite series of complex terms which converges but not absolutely. Then can we still break it up into its real and imaginary parts? $$\sum a_n = \sum x_n + i\sum y_n$$
