How to plot multiple functions on the same figure

Question

How can I plot the following 3 functions (i.e. sin, cos and the addition), on the domain t, in the same figure?

import numpy as np
import matplotlib.pyplot as plt

t = np.linspace(0, 2*np.pi, 400)

a = np.sin(t)
b = np.cos(t)
c = a + b

Answer 1

To plot multiple graphs on the same figure you will have to do:

from numpy import *
import math
import matplotlib.pyplot as plt

t = linspace(0, 2*math.pi, 400)
a = sin(t)
b = cos(t)
c = a + b

plt.plot(t, a, 'r') # plotting t, a separately 
plt.plot(t, b, 'b') # plotting t, b separately 
plt.plot(t, c, 'g') # plotting t, c separately 
plt.show()
