How the symmetric and antisymmetric have results: A=0,G=H and B=0,G=-H in last picture ?

Take a pencil and a paper then try drawing the symmetric one first where you have to substitute A=0, G=H into $\psi_1$, $\psi_2$, and $\psi_3$. How does the resulting curve looks like if you make the $x=0$ line as a symmetrical line? Do the same for antisymmetric solution.
