The formula provided in the image is for calculating the Fourier series coefficients in the complex form. Let's break it down:

### Formula for Fourier Series Coefficients:
\[
D_n = \frac{1}{T_0} \int_{T_0} x(t) e^{-jn\omega_0 t} \, dt
\]

where:
- \( D_n \) is the Fourier coefficient for the \( n \)-th harmonic.
- \( T_0 \) is the period of the function \( x(t) \).
- \( x(t) \) is the periodic function being analyzed.
- \( \omega_0 = \frac{2\pi}{T_0} \) is the fundamental angular frequency.
- \( j \) is the imaginary unit.
- \( n \) is an integer, representing the harmonic number.

### Solution Steps:
1. **Identify the function \( x(t) \) and its period \( T_0 \).**
2. **Determine the fundamental frequency \( \omega_0 = \frac{2\pi}{T_0} \).**
3. **Compute the integral for each \( n \):**
   \[
   D_n = \frac{1}{T_0} \int_{0}^{T_0} x(t) e^{-jn\omega_0 t} \, dt
   \]

To proceed with solving this, we would need to know the specific form of \( x(t) \). 

If you provide the function \( x(t) \), I can help you calculate the Fourier coefficients. Would you like to proceed with a specific example?

### Follow-Up Questions:
1. What is the specific function \( x(t) \) you want to analyze for Fourier coefficients?
2. Are you looking for a general expression for the Fourier coefficients or specific values for certain \( n \)?
3. Would you like to see an example calculation for a standard function like a square wave or a sine wave?
4. Do you need the calculation for both the amplitude and phase of the Fourier coefficients?
5. Are there any particular properties of Fourier series or transforms you want to explore further?

Understanding the role of each component in the Fourier series formula helps in analyzing periodic signals in both time and frequency domains.
