1. Plot of sin(x) vs x:

The plot of sin(x) vs x is given below, which is the output of the code that follows:

import numpy

from numpy import sin, pi

from matplotlib import pyplot as plt

x = numpy.linspace(-2*pi,2*pi,100)

ysin=sin(x)

def Create_plot(c, v):

  plt.plot(c,v)

 plt.ylabel("sin(x)")

 plt.xlabel("x")

 plt.title('Plot of sin(x) from -2pi to 2pi')

 plt.show()

Create_plot(x,ysin)

The output for the adjacent code is give below:

[157, 91, 235]

[128, 80, 200]

[53, 35, 80]

X = [[1,5,10],

    [2,4,8],

    [1,2,3]]

Y = [[2,6,10],

    [9,7,5],

    [11,5,20]]

product = [[0,0,0],

          [0,0,0],

          [0,0,0]]

for i in range(len(X)):

  for j in range(len(Y[0])):

    for k in range(len(Y)):

       product[i][j] += X[i][k] * Y[k][j]

for p in product:

 print(p)
