## Definition
If $$f$$ integrable on $$[a, b]$$ for all $$b>a$$ and
$\lim _{b \rightarrow+\infty} \int_{a}^{b} f(x) d x$

$\int_{a}^{+\infty} f(x) d x=\lim _{b \rightarrow+\infty} \int_{a}^{b} f(x) d x.$

Finding popular branchings in vertex-weighted digraphs
Popular matchings have been intensively studied recently as a relaxed concept of stable matchings. By applying the concept of popular matchings to branchings in directed graphs, Kavitha et al. (2020) introduced popular branchings. In a directed graph G=(V_G,E_G), ... | {} |

implicit Partial differentiation
Hi,
I have a problem that has to do with implicit partial differentiation. I was wondering how I could solve it using Jacobian determinants, if not possible, then a straight forward approach is okay. Here we go!

### Introduction¶
A somewhat neglected model in the Data Science/Machine Learning community are Multivariate Adaptive Regression Splines (MARS). Despite being less popular than Neural Networks or Trees, I find the concept of MARS pretty interesting, especially because it comes as a fully linear model and thu... | {} |
For Any Two Sets a and B, Prove the Following: a ∩ ( a ∪ B ) ′ = ϕ - Mathematics
For any two sets A and B, prove the following:
$A \cap \left( A \cup B \right)' = \phi$
Solution
$LHS = A \cap \left( A \cup B \right)'$
$= A \cap \left( A' \cap B' \right)$
$= \left( A \cap A' \right) \cap \left( A \cap B' \right)$

# How do you find the domain of y = 3 - sqrtx?
Domain: $x \ge 0$ or $\left[0 , \infty\right)$
$y = 3 - \sqrt{x}$
Domain: under root to be $\ge 0$.
So Domain is $x \ge 0$. In interval notation: $\left[0 , \infty\right)$ | {} |
# Find the limit and derivative of integral function.
$\psi_m(x)$ is defined as $$\int_0^{\ln|x|}e^{mt}\sin(t)^m\mathop{dt}$$ with $m$ a natural number greater then zero. Now the question is, does $\lim\limits_{x\to 0}\psi_m(x)$ exist. I've tried using the squeeze theorem using $-1\leq \sin(t)^m\leq 1$ and this result... | {} |

# Short lattice vectors orthogonal to a random vector
Let $N$ be some prime number. Suppose I draw $s$ elements $g_1,..., g_s$, where each $g_i\in [N]$ is taken uniformly from some interval $I_i$ of size, say $\sqrt{N}$.
