Start by importing:

import numpy as np, numpy.random as npr, numpy.linalg as la import scipy.stats as st import matplotlib.pyplot as plt plt.rc('axes', axisbelow=True) def disp(*args): print(*(f'{a:.3f}' if isinstance(a,float) else a for a in args)) np.set_printoptions(precision=4, floatmode='fixed', suppress=True)

Calculate using python:

(dg stands for diagonal matrix and tr stands for trace)

1. Ax + y

2. (A + 2BT^T)x + 2x - 3y

3. x^Ty - dg(A) * x - 5 tr(B)

4. 2

5. diagonal between x and y in degrees
