I am a PhD student (not in maths). I have recently encountered a problem in my research which requires a solution to the following integral question:
================================================== =========================
Let:
Find an expression or approximate expression of several terms for the following integral:
================================================== ==========================
It looks like a classical question, and must have been solved by mathematicians long time ago. However I am not a maths student, so I don't know.
If someone in this forum knows, please tell me. Exact solution or approximate solution with several terms are all OK.
Any solution must be in general form involving those 4 parameters.
Or please tell me about any journal article or maths textbook that discuss this question or similar question. Thank you!
