a) Explain what the program below performs line by line: import numpy as np import matplotlib.pyplot as plt def f(t,x): return 2*x+4*np.exp(2*t) t min = Ot max 3 N= 100 delta t (L_max t_min)/N t= np.linspace (t_min, t_max, num =N+1) x - np.zeros (N+1) x [0] = 2 for i in range (N): x[i+1] = x[i] + f(t[i],x[i]) *delta t plt.plot(t, x, label='x') plt.legend ()

Which of the following is correct? O nlgn = 0(n) O 3n = 0(2") O nlgn = m(n) O 1000n2 = 0(n2)

Thanks a lot for your answer, but the output is far from what i wanted,  "Open conversation" is together  To edit my Question above, i think its better if its start from conversation to Open and then conversation to Open and so on,  i want to go through it all...   here more details for you--- conversation #FAQ_Saturday_Branch @acc-inv:دوام الفروع متى يداومون 09/21/2022 @ 2:50 PM   Open ----------------------------- then : conversation #FAQ_Branch_Working_Hours @duration:متى متى دوام الفروع عندكم 09/21/2022 @ 2:50 PM   Open -------------- then :    conversation #FAQ_Branch_Working_Hours @duration:متى صالات المطار 09/21/2022 @ 2:50 PM   Open   ~AND SO ON~
