I recently asked a question on MSE and got this answer. It doesn't actually provide a solution to the mathematical problem posed but rather gives a practical workaround to use interpolation and numerical solutions.
The workaround turned out to be very good and I've implemented it in my simulation. I've upvoted the answer as such. However, it doesn't actually answer the question I asked which was to express the integral in a closed form.
Should I accept this answer on the post and therefore leave the question without a 'true' answer? Or should I leave the question without an accepted answer so that one day someone may come along and solve it, in the meantime not rewarding the person who helped fix my problem?
