I think you have answered my question. ThanksMark44 said:The three equations in the attachment represent a coupled system of three differential equations. There are not three variables - there are six, the three variables and the three derivatives of these variables.
Since the question is more about solving a system of differential equations, and less about relativity, I am moving the thread to the technical math section.
I noticed that as well. My guess is that it should be one of them, not both.dextercioby said:You have both t and tau. Did you mean to write only 1 variable?
MTW Exercise 6.9 is a problem set from the textbook "Mathematical Methods in the Physical Sciences" by Mary L. Boas. It involves practicing the use of the yes/no answer technique in solving mathematical problems.
The yes/no answer technique is a problem-solving strategy that involves breaking down a complex problem into smaller yes/no questions, which can be answered using basic mathematical concepts and logic.
To approach MTW Exercise 6.9, you should first carefully read the problem and identify the key information and what is being asked. Then, break down the problem into smaller yes/no questions and work through them one at a time. Finally, check your answers and make sure they are logically consistent.
Some common mistakes when using the yes/no answer technique include not carefully reading the problem, making incorrect assumptions, and not checking the logical consistency of answers. It is also important to use precise language and notation when answering yes/no questions.
You can improve your skills in using the yes/no answer technique by practicing with a variety of problems and seeking feedback from peers or a teacher. It is also helpful to break down complex problems into smaller steps and to check your answers for logical consistency and precision.
