SUMMARY

The integral \int_{0}^{\infty}e^{-it}J_{0}(2t)dt was evaluated numerically using Mathematica due to the unavailability of a suitable integral in existing tables. The integral tables referenced contained errors, specifically prohibiting the use of the e^{-it} term. The discussion highlights the importance of verifying integral tables and utilizing computational tools for accurate evaluations.

The Attempt at a Solution



Well, I went to the tables for this one and came up empty handed. I found an integral in a table that is almost this integral. The problem is that the integral I found cannot have an exp(-it) term in it...it only allows for exp(+it) terms.

Try taking the complex conjugate of the integral formula.
 
Thanks for the reply. It turns out that the table I was using had a mistake in it. I used mathematica to compute the integral.
