 Mar 11 comment How to prove that we cannot see more than 3 faces of an opaque solid cube simultaneously? +1. Makes sense! Mar 11 comment How to prove that we cannot see more than 3 faces of an opaque solid cube simultaneously? But you can see 3 faces by focusing on one corner.

OK. I am waiting for other solutions if any. Jan 21 comment How to find the closed solution for the following recursive vector equations? @heropup's solution in his comment seems to be much more better. Jan 21 comment How to find the closed solution for the following recursive vector equations? +1 but I am waiting for the complete solution. :-) Jan 21 comment How to find the closed solution for the following recursive vector equations? @heropup: I think it should be $\sqrt{k-1}$ rather than $\sqrt{k}$. Jan 21 comment How to find the closed solution for the following recursive vector equations? @heropup: You can submit it as your answer, but don't forget to write the process.
