Menampilkan Rumus Plot Trigonometri menggunakan NumPy, SciPy, dan Matplotlib

import numpy as np
import scipy.linalg as la
import matplotlib.pyplot as plt

# 1. Set x to a value, e.g., 5
x = 5

# 2. Compute the square and cube of x
square_of_x = x**2
cube_of_x = x**3
print(f"Square of x: {square_of_x}")
print(f"Cube of x: {cube_of_x}")

# 3. Set theta to an angle value (in radians)
theta = np.pi / 4  # This sets theta to 45 degrees (pi/4 radians)

# 4. Calculate sin(theta) and cos(theta)
sin_theta = np.sin(theta)
cos_theta = np.cos(theta)
print(f"sin(theta): {sin_theta}")
print(f"cos(theta): {cos_theta}")

# 5. Create a row vector meshPoints with 500 values evenly spaced between -1 and 1
meshPoints = np.linspace(-1, 1, 500)

# 6. The expression to get the 53rd element of meshPoints
element_53 = meshPoints[52]  # Python uses 0-based indexing
print(f"The 53rd element of meshPoints: {element_53}")

# 7. Produce a plot of a sinusoid and save it as a JPEG file
plt.plot(meshPoints, np.sin(2 * np.pi * meshPoints))
plt.xlabel('x')
plt.ylabel('sin(2πx)')
plt.title('Sinusoid Plot')
plt.grid(True)
plt.savefig('sinusoid_plot.jpg')  # Save the plot as a JPEG file
plt.show()
