Reformating an equation
I have the formula $ f= \frac{\pi exp\{-(y-u) \frac{\pi}{\theta\sqrt3}\}}{\theta\sqrt3[1+exp\{-(y-u) \frac{\pi}{\theta\sqrt3}\}]^2}$
I am trying to convert it into the form $exp{[\frac{...}{...}]}$ but I am getting stuck.
I understand that $…

Creative approoach to understanding advanced math notation
I was very pleased when I saw Hilbert curves and as a student I am interested to learn advanced mathematical concepts such as Hilbert spaces in an interesting and creative way.
In many papers I am finding terms like "Lipschitz domain", "sufficiently…

Joint distribution of sum of dependent Poisson distributions
We have three independently Poisson distributed random variables, $U, V, W$, with intensities $\lambda, \mu, \nu$. Now, define $X = U + W$, and $Y = V + W$. The task is now to find the joint pmf of $(X, Y)$. What I started doing was the…

permutation and the combination in the manusctip
I am quite wondered how someone writes the permutation/combination as the part of a formula in the manuscript?
For example, let $x$ be a set of values, $x=\{x_1,x_2,...,x_n\}$. Then if someone want to write the $\sum (\text{combination of two})…

What is the "optimal" use of rote learning in studying (pure) math?
This question is about efficiency of studying habits in math.
Clearly, rote learning everything without trying to develop an understanding of concepts in a math education is a bad idea, and this doesn't need an explanation.
On the other hand,…

what is sin(x) / abs(x) as x goes to limit of 0?
What is the limit value of $\frac{sin(x)}{|x|}$ as $x\rightarrow 0?$
I tried to solve this question by dividing it into two cases
$\mathrm{(i)} \ x>0,$ and $\mathrm{(ii)}\ x<0.$
When $x>0,$ the limit value goes to one, as we know.
But, when $x<0$…

Particular solution to a difference equation
I'm working through some excercises from Applied Econometric Time Series by Walter Enders.
In the book it is asserted that a particular solution to a difference equation $y_t=a_0 + a_1y_{t-1} + bt^d$ has the form $y_t = c_0 + c_1t + c_2t^2 + ... +…

Which one is more complex; $(1-e^a)^{(b^c)}$ or $\frac{e^a \times a^b}{b!}$
I know this is a simple question but I cannot find an answer for it. I have two functions,
$$1:\ (1-e^a)^{(b^c)}$$
and
$$2:\ \frac{e^a \times a^b}{b!}$$
where $a,c$ are real numbers, $b=1,2,3,...$, $log(e)=1$ and $b!=b(b-1) ... 1$.
which one…
