I am trying to plot these five curves in one plot. The problem is that one I do that the lines appear is if they are straight horizontal lines and they don't change as $a$ increases. Is there a way or scale to use to plot these five curves in one plot so that it appears they do change with $a$?
I hope you understand what I mean. Any help is appreciated.
