Let's say I want a formula that takes any number and makes it into 170, and I come up with a formula that I think does it. If I plug 1 into it, 2 int...

Okay, I know what you're thinking : this question has been asked a billion times before. But I have done my research, and sadly, the only answers I h...

let $W$ be a $n\times m$ matrix and $\textbf{x}$ be a $m\times1$ vector. How do we calculate the following then? $$\frac{dW\textbf{x}}{dW}$$ Thanks in adv...

Suppose i have a linear mapping from $L:\mathbb{R^2}_v \rightarrow \mathbb{R^2}_w$ and in $ \mathbb{R^2}_v$ i chose the standard basis and a vector is rep...

A very general question, I apologize, but as you read this, hopefully you get what I'm asking. Recently, Bernoulli Numbers have caught my eye, for I ...

I'm struggling with the following problem: In order to calculate $\int_{a}^{b}f(x)dx$ we use the Gaussian quadrature formula $\int_{a}^{b}f(x)dx\appr...

I am reading a paper, in the context of computer vision, that mentions the "famous" Dirichlet energy. I am not familiar with this Dirichlet energy, but ap...

Example 1 $\displaystyle \lim _{x\rightarrow -\infty }\frac{\sqrt{9x^{2} +2}}{2x-9}$ Example 2 $\displaystyle \lim _{x\rightarrow -\infty }\frac{6x^{2} -x...

Is it possible to find out that which of two sides are parallel in this irregular decagon.If,it is yes;then how can I proceed? I have tried with "Consecut...

Suppose $Y \sim \mathrm{Bin}(n,p)$ given $\Theta=(p,q)$ and $Z \sim \mathrm{Bin}(y,q)$ given $Y=y$ and $\Theta=(p,q)$. Now I want to determine the varianc...
