Rrenormalize replied to the thread I Trigonometry problem of interest.Good catch. To eliminate solution triples that are integer multiples of other triples I must verify that either ##b## or ##x## (or both)...

Like.
@renormalize Thank you very much. :) You did verify the 3 combinations that I had previously found, plus the one in the Olympiad. You... -
Rrenormalize replied to the thread I Trigonometry problem of interest.@Charles Link, given that ##a\geq1,b\geq1##, you can solve your formula ##(a+2b)^2=3(4x^2-a^2)## to get...

Rrenormalize reacted to DaveC426913's post in the thread Who is responsible for the software when AI takes over programming? with Like.
I still don't follow this logic. Why not? Note: we're not improving the AI per se; we're improving the product - the code it writes...

Rrenormalize reacted to TSny's post in the thread I Does Poisson's equation hold due to vector potential cancellation? with Like.
In your example in post #1, ##\large \frac{\partial A_y}{\partial y} \neq 0## for points along the x-axis. So, ##\nabla \cdot \mathbf{A}...

Rrenormalize replied to the thread In the early days of electricity, they didn't have wall plugs.Agreed, one could modify a standard two-terminal light socket to accommodate a ground terminal and make an adapter that would then...

Rrenormalize replied to the thread In the early days of electricity, they didn't have wall plugs.OK, that's a fair observation. But for those sockets, to which terminal would it be proper to connect a green (in the US) ground wire...

Rrenormalize replied to the thread In the early days of electricity, they didn't have wall plugs.I don't think those modern adapters have a ground wire either. I've never seen a light socket that could accommodate any additional wire...
