 11h comment The probability distribution @AndyK I don't think that this is a $LaTeX$ specific term. It is about programs in general and describes a chunk of code that "will allow readers to copy-and-paste-and-compile your code and see exactly what problems you might be experiencing". I can't see how this is useful in this context. 13h comment The probability distribution Please show us your efforts. 14h revised The probability distribution inlining image 14h revised Is my approach correct deleted 2 characters in body 14h revised Is my approach correct deleted 2 characters in body 14h revised Is my approach correct format latex 14h comment I want to show that $x^2 - x + C\epsilon\ge 0$ under some assumption. if $x=5$ what is your sufficiently small $\varepsilon$? 14h comment I want to show that $x^2 - x + C\epsilon\ge 0$ under some assumption. That sentence make no sense. If yo want to assume that $x \le 1/2 \sqrt\epsilon$ then assume it. But again, your formulation does not make no sense. 14h comment I want to show that $x^2 - x + C\epsilon\ge 0$ under some assumption. "Let $x\ge 0$. For sufficiently small $\epsilon>0$, assume that $x\le \sqrt\epsilon$." That does not make sense. Given $x$ you have to make $\epsilon$ sufficiently large, to make $\sqrt\epsilon$ greater than $x$, not to make it sufficiently small. Or maybe you want to say only "Assume that $x\le \sqrt\epsilon$" 1d reviewed Approve Problem on this Geometry question Apr 30 reviewed Approve Problem involving subspaces and linear transformations Apr 29 comment Why is The Following equality true?

Apr 28 comment Right Triangle's Proof But if you check this three cases you get $b^2$ is $63$, $44$ or $23$. So 12 actually can't be the lenght of the hypotenuse because none of these numbers is a perfect square. Apr 28 comment Right Triangle's Proof No, I said if you want to check if 12 is the length of the hypotenuse $c$ you only have to check the three cases where $a$ is $9$, $10$ or $11$.
