Peskin & Schroeder's 2.2c) Solution: Charge of the Complex Scalar (Klein-Gordon) Field

In this video I will solve Peskin & Schroeder's 2.2 c) solution: Rewrite the conserved charge in terms of creation and annihilation operators, and evaluate the charge of the particles of each type.

@11:39 (when applying the dirac delta) I miss a 1/2, which was part of the x-Integral. Why is this gone ?

Hi
How can I solve the quantum oscillator problem with potential v(x, y)= kx²/2+ky²/2-kxy?
