comment Establish a trigonometry-based $floor$ function
@barak: all I can say is, do not use the $\lceil \cdot\rceil$ notation when you do not actually mean the ceiling function.

comment Establish a trigonometry-based $floor$ function
@barak: yes, and $\lceil x - 1\rceil = \lceil x \rceil - 1$. The rest I certainly hope you can do by yourself.

comment Establish a trigonometry-based $floor$ function
@barakmanos: $\lceil x \rceil = - \lfloor -x \rfloor$.

comment Newton-Raphson method fails!
A side comment: you may want to instead ask your question at scicomp.stackexchange.com But you should give more details about your problem, for example what the function $R(x)$ is, and some details about your implementation, and when you say that it fails to converge, what are the values of $x$ and $R$ in the iterations.

@Martín-BlasPérezPinilla: $R$ is the current value of the function.

comment A planar Brownian motion has area zero
Wow, what an answer. Just for future reference, you may find it useful to draft your response using our sandbox for long answers. It helps the community in that by lowering the number of edits, you free up some real-estate on the front page for other questions. Thanks!

comment What do we mean by the term “Number of things”?
@CoolHandLouis: I have some doubts that Professor H.B. Fine was confused. :-p But there are indeed some inexactitudes in his book.

comment How many solutions are there to $2^a + 3^b = 2^c + 3^d$?
@Vor: regarding your flag, seeing that it has been open for more than a week, I can only tell you that the moderators have not been able to decide whether to carry out the migration. This is mostly due to Ross Millikan having point out the relevant OEIS entry. I encourage you to actually post a request to meta.mathoverflow.net asking directly whether this question would be considered to be on-topic for migration. If you receive a positive answer there, please flag again and we will be happy to move it over for you.
