Integration with Bessel function

Click For Summary
SUMMARY

The discussion centers on evaluating the integral involving the Bessel function J_{3}(\lambda_{m}r) and an unspecified function α(r). The integral is defined as ∫^{a}_{0} α(r)rJ_{3}(\lambda_{m}r)dr, which is part of a larger problem related to solving the wave equation in polar coordinates. Participants emphasize the importance of knowing the specific form of α(r) to determine the appropriate method for evaluation, such as using a recurrence relation. The conversation also highlights the necessity of adhering to homework guidelines when approaching such problems.

I would like to evaluate the following integral which has a Bessel function J_{3}(\lambda_{m}r), and \alpha(r) is a function.

\int^{a}_{0} \alpha(r)rJ_{3}(\lambda_{m}r)dr

I'm unsure how to proceed due to the Bessel function. Am I supposed to use a recurrence relation? Which one?

It depends on what the function α(r) is.
 
The integral is part of a larger problem, which is to solve the wave equation in polar coordinates. The problem statement does not specify α(r).

Should I just leave the integral as is?
 
If this is homework, follow the homework template. We're not here to guess what you should or should no be doing.
