Hello, how would you derive the solutions of the twin delta function potential:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]V(x) = -g \delta(x+a) + \delta(x -a ) [/tex]

?

Obviously the solutions outside the potential are Ae^Kx for x less than aand A e^-Kx for x greater than a. But how do you derive the hyperbolic cosine function for the interval between -a and a? Please use symmetry arguments because I need to understand those!
