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

Solution

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

Function 1:

\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.
