Question

Need to use numpy to create this graph. I have the following code but am unsure of how to graph the intersection points:

import random
import matplotlib.pyplot as plt
import numpy as np
x4 = np.linspace(0,6*np.pi,200)
plt.plot(x4,x4)
plt.plot(x4,x4*np.sin(x4))

Plot the functions y = x and y = x sin(x) over the interval [0, 67], and add the red dots to create this figure

Expert Solution

Step 1

To graph the intersection points of the two curves, you can first find the x-coordinates of the intersection points using numpy's intersect1d function. Here's an example code snippet:
