1、对数函数

import math
import matplotlib.pyplot as plt
import numpy as np
if __name__ == \'__main__\':
    x = np.arange(0.05,3,0.05)
    y1 = [math.log(a,1.5) for a in x]
    plt.plot(x,y1,linewidth=2,color=\'#007500\',label=\'log1.5(x)\')
    plt.plot([1,1],[y1[0],y1[-1]],"r--",linewidth=2)
    y2 = [math.log(a,2) for a in x]
    plt.plot(x,y2,linewidth=2,color=\'#9F35FF\',label=\'log2(x)\')
    y3 = [math.log(a,3) for a in x]
    plt.plot(x,y3,linewidth=2,color=\'#F75000\',label=\'log3(x)\')
    plt.legend(loc=\'lower right\')
    plt.grid(True)
    plt.show()
