Python Graph tan and arctan with python

[ver_mathstats]

import numpy as np
import matplotlib.pyplot as plt

x=np.arange(-5*np.pi, 5*np.pi, step = 0.02)
plt.ylim(-1, 1)
tan=np.tan(x)
arctan=np.arctan(x)
plt.plot(x,tan)
plt.plot(x,arctan)

Here is the code I came up with using the guide my teacher gave me, is this correct the way I have done it? Thank you.

Can't you run it and see?

Yeah I did, and it went fine I think, I just wanted to make sure it was okay. Thanks for the response though.

It looks good to me. I just wanted you to test it for yourself.

You showed that you understand that arctan is the inverse of tan, but if you want us to evaluate your code, maybe you could show some of its output.

Oh okay, like attaching a photo of the results I obtained?

Maybe a text copy would be better than a screenshot, but the point is that for diagnostic purposes, we're better informed if we can see all of the components -- input, code, and output.

If you add a line that says:

plt.savefig("myplot.png")

it will save the plot as a png file which you can then attach to your post using the "Attach Files" button.
