 1d revised Why $-1 \leq\frac{\langle A,B\rangle}{||A||\, ||B||}\leq1$? added 2 characters in body 1d answered Why $-1 \leq\frac{\langle A,B\rangle}{||A||\, ||B||}\leq1$?

All you are doing is re-expressing one set of expressions in an equivalent form using more symbols? Mar15 comment Compute $\int_{0}^{e}\sin(\pi\ln(x))dx$ @ChristophS No problem, glad I could help!

Mar6 comment Solve Laplace's equation inside a semi-infinite strip @JessyWhite Sorry, I missed out the minus sign! The minus sign is important as it means the solution decays as we approach infinity. This is the significance of the half-infinite $x$-dimension Mar6 revised Solve Laplace's equation inside a semi-infinite strip added 1 character in body Mar6 answered Solve Laplace's equation inside a semi-infinite strip Mar1 reviewed Leave Open How do I interpret this density function Feb17 comment 2-Dimensional FOURIER TRANSFORM Your $y$ variable appears in both $g(x,y)$ and $G(w,y)$? Is that right? Feb3 comment In how many ways can we distribute 6 identical pears? @Rick No problem; glad it helped! Feb3 comment In how many ways can we distribute 6 identical pears? @Rick I am using the second form, with $n=3$, $k=6$; as we are using Theorem 1 on the Wikipedia page, as we want positive numbers of items in each bin, rather than non-negative (which include zero). Feb3 comment What is the limit of this complex expression? I am unfamiliar with complex analysis, but what you have done seems correct to me; but the $j$ is a prefactor which can be pulled out of the limit, and we have $jx = 0 \iff x = 0$ and thus what they are trying to find will be equivalent. Feb3 comment In how many ways can we distribute 6 identical pears? @HenningMakholm There are $6$ pears, and so we have $5$ places in which we can place the dividers, and we wish to place $2$ dividers in order to create three separate multisets, thus giving us $\binom{5}{2}$ Feb3 answered In how many ways can we distribute 6 identical pears?
