编写代码以使CPU使用率显示正弦波

import time
import math
import os

while True:
    start_time = time.time()
    for i in range(1000000):
        math.sin(i)
    end_time = time.time()
    elapsed_time = end_time - start_time
    cpu_usage = os.getloadavg()[0]
    print(f"Elapsed time: {elapsed_time}, CPU usage: {cpu_usage}")
