Proof of satellite revolve around earth in circular path

[Steven7]

Hi guys. I do not know artificial satellite revolve around Earth in a circular path or an ellipse path but do we have physics and mathematical proof that artificial satellite revolve around Earth in circular/ellipse path?

Yes, it's the exact same as the proof given hundreds of years ago by Newton that the planets orbit the sun in ellipses (note, a circle is just a special case of an ellipse).
