Hi, I need to state the given relations on two graphs in titles (the ones that are written below), x (omega) and y (y cap ej omega) labels but the representation of hat confused me. It is written that this can be provided with latex yet I don't know how to represent those fully by using latex and plotting those in italic. By the way, given relations are the representations of two different graphs. Consequenttly, how can I write those in titles, x and y labels, respectively?
Thanks in advance.
