**Title: Analyzing Fourier Series Representations**
**Introduction to Fourier Series:**
The Fourier transform is a fundamental tool in mathematics and signal processing, allowing us to represent a 2π-periodic function in terms of its sine and cosine components.
**Task:**
`f` is a 2π-periodic function with the following Fourier coefficients:
\[
\begin{aligned}
a_0 &= 0 \\
a_1 &= \frac{1}{3}, \quad b_1 = 0 \\
a_2 &= 0, \quad b_2 = 0 \\
a_3 &= 0, \quad b_3 = 0 \\
\end{aligned}
\]
**Question:**
Which of the following is the graph of \( f \)?
1. **Graph A:** Displays a waveform with more than one oscillation per period, suggesting the presence of higher harmonics.
2. **Graph B:** Shows a waveform with a smooth, single oscillation that closely matches the first sine component, suggesting that this is likely the correct graph since we only have an \( a_1 \) term.
3. **Graph C:** Features a waveform with less oscillation than Graph A, but more than Graph B, indicating some additional harmonic content.
4. **Graph D:** Exhibits a smooth waveform with minimal oscillation, but seems slightly more complex than a single harmonic.
**Conclusion:**
Based on the given coefficients indicating only a first harmonic (sine wave) contribution, Graph B is most likely the correct representation of \( f \).
