Thanks @Gavran for pointing out those cases. In my formulation, I computed the largest petal and the next largest petal which accounts...

The formula ## f=(\pi/5+\sin72^\circ/2-2\sin72^\circ\sin^236^\circ)/(\pi/5+\sin72^\circ/2)\\ ## from post #6 can be transformed into a...

I worked up the general case for integer ##n## overlapping circles. Here is the Desmos page; The red circle is the generator of the...

Aagh. Misread the question. Post struck-through.

With complex numbers, it makes it even easier,...

My answer was actually <0.4 at about 0.3974 so I am investigating my math… EDIT: I did the calculation another way and agree with @Gavran.

Consider a disc of radius ##R## with a uniform mass distribution and total mass ##M## rotating in its own plane. In its COM's inertial...

Make the radii of the holes tend to zero: we have a body tending to look close to a coin. If all the molecules of coin increase at once...

That is correct. The EMF in the wire is not due to an E field. The EMF in the wire is due to the Lorentz force on the charges in the wire.

Given that AI can screw up on math due to hallucinations, it would be fun if there was a channel dedicated to making AI screw up, or...

You are correct. Mechanical energy can be potential energy too. Elastic energy is the mechanical potential energy, but it does not...

Thank you very much for the explanation Rap and Gavran

I am unsure of what to say here. There are those who will tell you that Vbf is equivalent to Vb - Vf, and there are those who will tell...
