Let γ(θ) and φ(θ) be arbitrary functions of the angles θ which have the property that γ(θ)=λ(θ+2π) and φ(θ)=φ(θ+2π) , since the angles θ andθ+2π are physically identical. Demonstrate that the operator G=id/dθ (partials) is Hermitian if θ spans the angularrange from 0 to 2π radians (integrate the integral<γ/G/φ> by parts to show that it equals).
