 So you must know that P is constant, it's not like only single piece is there for a time loop. That's why you can be with it perfectly. Get in it, that will come up, you might have never seen that. So let's, those fundamental questions, they do come. And then something clear, it should be true. So from there on he formatted something and it happens to be true. On the loop you'll find it. Understood? Yes, sir. Yes, sir, we can talk. Sir, do you understand this sentence? Understood? Okay. So you have a number of people. So if you subtract that that's going up, from what is going down. That's into pi into r squared minus a squared. This is the current, this one. When you substitute it over here, you take the value of p. If you conjugate it over here.
