The Triple Integration Techniques.

The Gaussian integral may be shifted vertically in the complex plane because the vertical sides of the contour contribute vanishingly in the limit.

My girlfriend borrowed some money from me saying it was for her mother’s medical emergency. Turns out she used it to go on a trip with another guy. I found hotel bookings and flight confirmations. Instead of confronting her, I planned to send the evidence to her family group
