Integral Value Calculation: Physics Problem Solving

In summary, integral value calculation is a mathematical process used in physics to determine the area under a curve or the volume of a solid. It involves breaking down complex shapes or functions into smaller parts and adding them together to find the total value. The steps involved in solving a physics problem using integral value calculation include identifying the physical quantity or problem, setting up the integral, evaluating it, and interpreting the solution. However, some common challenges in using this method include understanding and correctly applying integration, selecting the appropriate integral, and dealing with complex shapes or functions. To improve skills in integral value calculation, it is recommended to practice regularly, have a strong understanding of integration principles, use visual aids, and seek help when needed.

The "value" of the integral is infinity, a.k.a. it does not converge.
Only for sin(kr)/r one can do the integration. Are you sure this is not what you meant? It looks like the typical integral coming from an integration over all space in spherical coordinates, which also introduces a Jacobian of r^2 sin(theta).
