# Matrix Representation: Hamiltonian of the Infinite Square Well

Consider the eigenstates of the infinite square well defined by

V(x<-a/2) = infinity

V(-a/2 < x < a/2) = 0

V (x> a/s) = infinity

a. If the Hilbert space base-kets for this potential are seen in the attachment. Write down the matrix representation for the Hamiltonian H-hat of the system.

b. What is the matrix representation for the parity operator P-hat?

c. Use the matrix representation to verify the commutation relation [H-hat, P-hat]=0
