SUMMARY
The series \(\Sigma_{n=1}^{\infty} \frac{\sin(nx)}{n^2}\) is continuous on \(\mathbb{R}\) due to its uniform convergence. The discussion emphasizes that demonstrating uniform convergence is straightforward, which directly leads to the conclusion of continuity. The participant indicates that the use of uniform convergence is permitted, simplifying the proof process significantly.
