SUMMARY
The discussion focuses on the integration of the function e^{3x} cos(x) using the technique of integration by parts, specifically applied twice. The user successfully derives the integral as \int e^{3x} \cos{(x)}\; dx = \frac{e^{3x}\sin{(x)} + 3e^{3x} \cos{(x})} {10}. This solution confirms the correct application of integration by parts, demonstrating the method's effectiveness in handling products of exponential and trigonometric functions.
