Homework Help: Kinetic Energy operator is hermitian

  1. Sep 25, 2013 #1
    The problem asks to show that the kinetic energy operator is Hermitian.

    The operator is given as T= -h^2/2mΔ but I know I can also write it as p^2/2m which would be

    (- ih∇)(-ih∇). My main question is if I can prove this in 1-D so that T=(-h^2/2m)d^2/dx^2
    does that generalize to 3-d? Is it proven in 3 dimensions then? If not I'm not sure where to even begin in 3D
