I'm researching the different execution time of various sorting algorithms and I've come across two with similar times, but I'm not sure if...

I was looking to the volume created if I revolve the area of the pentagon having vertices (1,0), (2,2), (0,4), (-2, 2), (-1,0) about the x-axis. My work: ...

If $p^3+p=q^2+q$ where $p$ and $q$ are prime numbers, Find all the solutions (p, q) I tried to solve this exercise using that: $p^2 = -1(\text{mod} \, q)$...

Apparently $E[X] = E[E[X\mid Y]]$ but I don't understand what this really means. I looked at https://en.wikipedia.org/wiki/Law_of_total_expectation b...

Recently, when asking for the derivative of angular momentum, I gave my own solution $$ \frac {d \vec L} {dt} = \frac {d \vec r_{(t1)}} {dt} \times \frac ...

How would you write a fraction in binary numbers; for example, $1/4$, which is $.25$? I know how to write binary of whole numbers such as 6, being $110$, ...

I have seen two versions of incompleteness that follow from the correctness of a system and its power (i.e. of a system that satisfies the assumptions of ...
