 Dec11 answered Why $2\sqrt{x} + \sqrt{3}$ can’t be simplified any further? Dec9 comment Trick to find multiples mentally @ArturoMagidin Yes, I meant multiples. It's corrected.

Please add the "homework" tag if it is so. Nov21 accepted Why isn't a harp in a logarithmic shape? Nov10 asked Why isn't a harp in a logarithmic shape? Nov1 answered Universal binary operation and finite fields (ring) Nov1 comment Path from $(1,1)$ to $(4,4)$ with least number of lattice points within a certain distance Maybe you should think of a better name for your question. This one is too vague. Nov1 comment Path from $(1,1)$ to $(4,4)$ with least number of lattice points within a certain distance +1 for iterative thinking, I think it may be the only way to prove that: first from $(1;1)$ to $(2;2)$, then to $(3;3)$ and then to $(n;m)$ Oct31 revised How to equally divide a circle with parallel lines? It IS quite simple with a computer Oct31 comment How to equally divide a circle with parallel lines? After integrating: $r^2 \cdot \arctan(\frac{\sqrt{v_i}}{\sqrt{2 \cdot r - v_i}}) - \frac{\sqrt{v_i} \cdot (r - v_i) \cdot \sqrt{2 \cdot r - v_i}}{2} = 1/2 \cdot \pi \cdot r^2 \cdot \frac{i}{n}$. (Of course, it may be easier to read with proper values for $r$, $i$ and $n$). Then, isolating $v_i$ is algebra I won't do it here. Oct31 comment How to solve $x\cdot\mathrm e^x=1$? Thank you for this different approach. That was not at all what I was looking for, but +1 anyway, because I think it's cool and gives a good approximation of values. Oct31 comment How to equally divide a circle with parallel lines? @TonyK intergate, keeping $v_i$ as a variable and then find $v_i$…
