It would be nice to point out exactly what does not work. Because in fact, everything turns out great:
import matplotlib.pyplot as plt import numpy as np import math xi = np.arange(-25, 25, .001) yi1 = [math.sqrt(x - x**2 + 1) if (x - x**2 + 1)>=0 else float('nan') for x in xi] yi2 = np.tan(xi) plt.figure(figsize=(10,4)) plt.ylim([-10, 10]) plt.grid() plt.plot(xi, yi2) plt.plot(xi, yi1)
