Time-independent Superposition and Expectation Values: Infinite Square Well 

(Illustration)

n1 =   n2 =  

The superposition shown is an equal mix of the two states n1 and n2 for the infinite square well, Yn1n2(x)=(1/2)-1/2 [fn1 (x) + fn2 (x)].    Vary n1 and n2 keeping n1<n2 to avoid duplicating states, and also avoid n1=n2.
