I wrote this Python code and the graph won't display. I can see the box for the graph but nothing is graphed. I tried to convert to an array but still no results. Please help.

My code is :

import math

import matplotlib.pyplot as plt

import numpy as np

j = np.arange(.1,1)

k = np.asarray(j)

a = math.sqrt((0.02358/k)-0.0189)

b = -(0.054)*50*math.exp(-0.054*50)

c = (50*a*math.cos(50*a))+math.sin(50*a)

d = math.exp(-0.054*50)

e = math.sin(50*a)

determinant = (b*e)-(c*d)

plt.plot(k, determinant)

plt.xlim([0,1])

plt.ylim([-5,5])

plt.xlabel('k value')

plt.ylabel('Determinant')

plt.show()
