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

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

解決方案

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()
