1. The problem statement, all variables and given/known data Let V be the set of all complex-valued functions f on the real line such that (for all t in R), f(-t)=f(t) with a bar on top (can't figure out Latex, sorry) The bar denotes complex conjugation. Give an example of a function in V which is not real-valued. 2. Relevant equations 3. The attempt at a solution Not quite sure what this means, just need a place to start really.
