Well, the tittle is self-explanatory. If anyone has an interesting problem or puzzle. I will be grateful if you could post it.

I think I solved your problem. If you rearrange this equation you should get that r=(something)xd, where r is the radious of the field and d the length of the rope, that should be the relationship between the rope and the radius of the field. I hope I am right.CWatters said:A cow stands in a circular field of radius R. It's tethered to a post on the boundary by a rope. How long is the rope if the cow can eat half the grass in the field? Ignore length of cow.
And no I don't have the answer.
It can be done through integration, can't it?CWatters said:
Is it because they are linearly independent? Like how if you have y = sin(x) + cos(x) you can't isolate x?OmCheeto said:Why is it not possible to solve the equation: y = x - sin(x)?
Or is it simply because ##π## is transcendent?Mercy said:Is it because they are linearly independent? Like how if you have y = sin(x) + cos(x) you can't isolate x?
In my head I just expand out the power series for sine and then you end up with an infinite degree polynomial which can't be reduced, not sure if that's the answer though

Have you considered the fact that this might have been not your fault? I'm out for 20 years now and they leave nothing untried to shoot me down.OmCheeto said:I've posted in the Maths forum about twice, in the last 8 years. Both times, I sensed that people thought that I didn't quite speak right, so I never went back.
haha fair enough, do you remember what the answer you were satisfied with was?OmCheeto said:all bolding mine.
Perhaps you two should ask these questions in the "Maths" forum. I haven't spoken the language of maths in 30 years, so I have no idea what you two are talking about.

So basically we agree on: "It's getting uglier and uglier the more you try." Guess that's something for number theorists. They love those expressions.OmCheeto said:Upon showing this to my acquaintance, he told me that taking the inverse of an infinite series was uglier than the original infinite series.
A flat mirror reverses forwards and backwards (along a line perpendicular to the surface of the mirror), not left and right or up and down.fresh_42 said:Why does a mirror change left and right but not up and down?
An interesting physics or math problem is one that challenges our understanding of the natural world and requires creative thinking to solve. It should also have real-world applications and be applicable to various fields of study.
There are many resources available for finding interesting physics or math problems, such as textbooks, online forums and communities, and scientific publications. You can also create your own problems by applying your knowledge to real-world situations.
The best way to improve your problem-solving skills is by practicing regularly and challenging yourself with new and difficult problems. You can also seek guidance from experienced scientists or join study groups to discuss and solve problems together.
While there is no one-size-fits-all strategy for solving problems, some common approaches include breaking down the problem into smaller, more manageable parts, drawing diagrams or visual aids, and using equations and formulas to guide your thinking process.
Solving physics or math problems not only helps deepen your understanding of these subjects, but it also trains your critical thinking and analytical skills, which are essential for success in any scientific field. It can also improve your problem-solving abilities in other areas of your life.
