Excuse me, what do you mean with IFR and FR?

Don't certainly know, but I think I have to express the metric interval ##ds^2=c^2dt^2-dx^2## but in polar coordinates, because like you showed me, It's a disk. What do you think?

I haven't considered any reference because I've not been able to solve it, may need a little help

A large disk rotates at uniform angular speed ##\Omega## in an inertial frame ##S##. Two observers, ##O_1## and ##O_2##, ride on the disk at radial distances ##r_1## and ##r_2##, respectively, from the center (not necessarily on the same radial line). They carry clocks, ##C_1## and ##C_2##...

I think they assume that the velocity of ligth depends of source motion, like It was Galilean, I had an idea, I have to take an infinitesimal time interval, after that take an infinitesimal distance interval, and then divide it by the already calculated time interval, but it still doesn't give...

Yes, I did it. But I only come to the expression of the Doppler efect, but from that point to the expression above there's still a world of difference.

Hey, I have this problem from the Special Relativity by AP. French . Exercise 3.3, Chapter 3. The figure shows a double-star system with two stars, A and B, in circular orbits of the same period T about their center of mass. The earth is in the plane definied by these orbits at a distance R of...
