SUMMARY
The integral of (e^-ax)sin(bx) from 0 to infinity evaluates to zero when applying the limit as x approaches infinity. The solution provided is correct, confirming that the result is derived from the lower limit at x=0. The expression for the integral is given as \(\frac { \frac { -1 }{ a } { e }^{ -ax }\quad sinbx\quad -\frac { b }{ { a }^{ 2 } } { e }^{ -ax }\quad cosbx }{ 1+\frac { { b }^{ 2 } }{ { a }^{ 2 } } }\).
