That's because it's a mathematically identity. OP just can't math.

sequential posts speak the truth

Yea, I guess all of classical electrodynamics is fucked because the divergence and curl theorems are bullshit, am I right? OP double check your math, chances are you either can't integrate or you made a small mistake
