SUMMARY
The integral of the function int(exp(-x)*sin(a*x)/(x),x=0..infinity) cannot be solved using traditional integration by parts methods. Instead, it results in exponential integrals that involve complex numbers. The discussion highlights the necessity of utilizing incomplete gamma functions or numerical methods for accurate evaluation. Mathematical software is recommended for handling such integrals effectively.
