Is a matrix populated randomly by 0/1 invertible?
Suppose each entry of a $2\times 2$ matrix is populated with $0$ or $1$ independently with probability $1/2$. What is the probability that this matrix invertible? What will be the …
Your experience with AI for problem solving
What is the most challenging problem (according to you), which you solved completely using AI? Which model did you use? How many prompts did it take to get the desired solution?
What is the difference between the order of the local error and the global error of a numerical method to solve a PDE?
The order of local error is defined in the literature. But I am not getting the order of global error.
Range of self-invertible real valued function
Let \( f:\mathbb{R}\longrightarrow\mathbb{R} \) be a function of the form \[ f(x) = \dfrac{ax+b}{cx+d}, \quad\text{where}\quad a,b,c,d \neq 0 \quad\text{and}\quad cx+d \neq 0. \] F…
Recursion and sequences
Find the general term of the sequence defined by $x_0 = 3, \, x_1 = 4$ and $$ x_{n+1} = x_{n-1}^2 - nx_n $$ for all $n\in\mathbb{N}$.
Rate of convergence of Jacobi and Gauss-Seidel Algorithms
I am aware of the two cases: a) 2X2 matrices b) Stein-Rosenberg case (where a_ii>0, a_ij
Existance of Null set
What is the general meaning of the word "existence" in broader mathematical context? Does null set exist?
Expected number of records in a random permutation of [n]
Working through $\mathbb{E}[R_n] = \sum_{k=1}^n \frac{1}{k} = H_n$ — simulation matches, want a cleaner indicator-variable writeup.
Rank–nullity for infinite-dimensional spaces; where does it break?
The finite-dimensional proof leans on a basis argument. What's the right replacement when $V$ is not finite-dimensional?
A cleaner tiling argument for the 2×n board recurrence
I can get the recurrence $a_n = a_{n-1} + a_{n-2}$ via casework on the last column, but is there a bijective proof?
Write it the way you'd explain it to a classmate
Consider the following hypothesis testing for population mean $\mu$ when the population variance is $\textbf{unknown}$; \begin{align*} H_{o}:\mu=\mu_{0}\\ H_{1}:\mu > \mu_{0}. \end…
