  • In the integrand was the product of the exponentials, which, of course, was the exponential of the sum of terms like eL.

  • After all, if we plot the integrand, we can see that it is positive throughout the range 0 to 2π:

  • Moreover, if a meromorphic integrand has simple poles in the complex plane, it is impossible to choose an antiderivative continuous along every imaginable path in the complex plane – because of branch cuts in.

  • The formula above should be integrated over different frequencies with an appropriate weight, and the parameters of the integrand C0,T0 would depend on the frequencies.

  • Of course, to do it properly, you need to integrate over all the channels, as Lubos noted in #9: “The formula above should be integrated over different frequencies with an appropriate weight, and the parameters of the integrand C0,T0 would depend on the frequencies.”

  • I think the next step would be a change of variables where we want to replace n with (x-mu)/sqrt(mu) and we would do this by knowing that the probability density function is an integrand thus our rules of substation for integration would apply.

  • The quantity in parentheses is the integrand of the outer integral.

  • This use of double integrals to calculate areas may seem like excessive make-work, and using "1" as the integrand may seem boring, but this sort of analysis is the basis for everything we will do.
