![### Question 2: Fourier Series Coefficients of Periodic Signals
**Problem Statement:**
For the periodic signals shown in the graph, find the coefficients of the trigonometric Fourier series.
**Graph Description:**
The graph depicts a periodic signal that repeats every \(2\pi\) units along the horizontal time axis (t).
- The signal exhibits a linear increase and decrease within a single period.
- The waveform starts at \((-\pi, -1)\).
- It increases linearly, crossing the time axis at \( t = -\pi/4 \), reaching a maximum value of 1 at \( t = \pi/4 \).
- Then, it decreases linearly, becoming zero again at \( t = \pi \).
- This pattern then repeats, creating a symmetric waveform around the time axis.
The periodic waveform is characterized by alternating positive and negative slopes. The essential points along the x-axis (t) include \(-\pi\), \(-\pi/4\), \(\pi/4\), \(\pi\), and \(2\pi\).
**Task:**
Calculate the trigonometric Fourier series coefficients of the given periodic signal. The Fourier series representation can be expressed as:
\[ x(t) = A_0 + \sum_{n=1}^{\infty} \left( A_n \cos(n\omega_0 t) + B_n \sin(n\omega_0 t) \right) \]
Where:
- \( A_0 \) is the average (DC) component.
- \( A_n \) and \( B_n \) are the Fourier coefficients.
- \( \omega_0 \) is the fundamental angular frequency.
The calculation involves integrating the signal over one period to find the coefficients \( A_0 \), \( A_n \), and \( B_n \), which describe the amplitude and phase of the sinusoidal components of the waveform.](https://content.bartleby.com/qna-images/question/091efdc9-e15b-4ccc-8207-a2051acfb2c9/49c5814b-7134-4bc7-81d4-1206c47f09d9/k42rzq6_processed.png)
