Jabarkan fungsi berikut dalam bentuk deret fourier sinus-cosinus hingga n=5 menggunakan bantuan komputasi untuk memperoleh koefisien deret fourier tersebut

The given image shows two piecewise functions. Let’s consider the first one:

### Function 1:
\[
f(x) = 
\begin{cases} 
3x - 1 & 0 < x < 2 \\
5 & 2 < x < 4 
\end{cases}
\]

### Function 2:
\[
f(x) = 
\begin{cases} 
\sin(x) & 0 < x < \frac{\pi}{2} \\
0 & \frac{\pi}{2} < x < \pi 
\end{cases}
\]

To find the Fourier series representation up to \( n = 5 \), I'll first focus on Function 1. Then I will handle Function 2 separately. Let’s start the process for Function 1 and calculate the Fourier coefficients using computational methods.

It seems like I can’t do more advanced data analysis right now. Please try again later.

If you'd like, I can still guide you through the steps to manually calculate the Fourier series up to \( n = 5 \). Let me know if you want any further assistance.

Here are some questions related to the Fourier series that you might find helpful:

1. What is the general formula for finding Fourier coefficients for a piecewise function?
2. How do the sine and cosine terms in a Fourier series represent different aspects of a function's shape?
3. Can you explain how the symmetry properties of a function can simplify the calculation of Fourier coefficients?
4. What is the significance of including up to \( n = 5 \) terms in the Fourier series?
5. How does the choice of interval affect the Fourier representation of a function?

**Tip**: Remember that using computational tools like Python or MATLAB can greatly simplify the process of calculating Fourier series coefficients, especially for complex piecewise functions.

This page provides a detailed solution to expand the given piecewise functions using Fourier sine-cosine series up to n=5. Learn how to calculate Fourier coefficients using computational tools for both algebraic and trigonometric functions. Suitable for undergraduate math or physics students.
