Show that $y(t) = t$ and $g(t) = t \ln(t)$ are linearly independent

I am looking for a reference (book or article) that poses a problem that seems to be a classic, in that I’ve heard it posed many times, but that I’ve never seen written anywhere: that of the possibility of a man in a circular pen with a lion, each with some maximum speed, avoiding capture by that lion.

References to these sprts of pursuit problems in general would also be appreciated, and the original source of this problem.

- Spectra of restrictions of bounded operators
- Do any authors systematically distinguish between 'theorems' (which have 'proofs') and mathematical 'beliefs' (which have 'evidence')?
- Do any books or articles develop basic Euclidean geometry from the perspective of “inner product affine spaces”?
- Good book on integral calculus (improper integrals, integrals with parameters, special functions)
- Reference for a tangent squared sum identity
- Elementary geometry from a higher perspective

- Next book in learning General Topology
- Books for starting with analysis
- Transition between field representation
- Can anybody recommend me a topology textbook?
- Books or site/guides about calculations by hand and mental tricks?
- Reference for a proof of the Hahn-Mazurkiewicz theorem
- polynomial values take on arbitrarily large prime factors?
- Learning about the universe or special/general relativity
- What is the best way to define the diameter of the empty subset of a metric space?
- Eigenvectors of real symmetric matrices are orthogonal

Since you’re asking for a reference, perhaps this will do?

Wolfram Mathworld says the problem was listed by Rado in 1925. The reference is on the problem description page, here.

Here is a book on this type of problem

http://press.princeton.edu/titles/8371.html

it is also briefly mentioned in his other book “Euler’s Fabulous Formula”.

The book is Coffee in Memphis by Bollobas. It’s the first problem, and there are loads more :
