 Jul 12 revised Decomposite a vector field into two parts added 101 characters in body Jul 12 revised Closed form $\int_{a}^b \cfrac{1}{(1+x) \, \left[\ln(1-x)-\ln(1+x)\right]} \, \mathrm{d}x$ edited title Jul 12 revised Can $\sum_{x \in [0,1]} e^x$ be represented as an integral? deleted 12 characters in body; edited title Jul 12 comment Differentiating $y=x^{2}$ If the original term was $2$ of $x\mathrm{d}x$, wouldn't it have to be written out as $2x * 2\mathrm{d}x$ Why? If instead of $x\mathrm{d}x$ it was $x c$ should it end up as $2x * 2cx$ instead of $2cx$? Jul 10 comment What happens when a probability actually occurs? this youtube.com/watch?v=D1RzvXDXyqA should be of interest. Jul 10 comment What happens when a probability actually occurs? +1, awesome question, all these years never realised to wonder about this! Jul 10 comment Evaluate the limit $\lim_{n\to\infty} \left(\frac{3n}{3n + 1}\right)^n$ limits are evaluated not solved.

Jul 8 revised Closed form for $a_{n+1} = (a_n)^2+\frac{1}{4}$ edited title Jul 8 comment Symbol for “is associated with” "is associated with" in what respect, is the association two way, or just one way? Jul 8 comment Symbol for “is associated with” It is neater to have a symbol Jul 8 revised Proof of the continuous function having tangent plane has directional derivatives edited title
