# Mean Value Theorem
The Mean Value Theorem is considered to be among the crucial tools in Calculus. According to the theorem, if f(x) is defined and is continuous on the interval [a,b] and can be differentiated on (a,b), then we have at least one value c in the interval (a,b) wherein a<c<b and,
$f’\left ( c \right )... | {} |
# What happens if I slowly lower a dangling object into a black hole?
I could've sworn I've seen this question before, but I couldn't find it.
Suppose I have an object on the end of a really long string. I can slowly lower it near the event horizon of a black hole, then pull it back out. But if I lower it just below ... | {} |
# An introduction to biclustering
Tue 25 June 2013 by Kemal Eren
## Introduction
This is the first in my series of biclustering posts. It serves as an introduction to the concept. The later posts will cover the individual algorithms that I am implementing for scikit-learn.
Before talking about biclustering, it is n... | {} |

### Linear Regression
The linear regression model is a fairly simple model, nevertheless it is used in many applications.
What follows is a fairly mathematical derivation of the linear regression parameters.
Let us denote the observations as $y[n]$ and $x[n]$ for $n=0,1,..,N-1$ for th... | {} |
uniform matroids and MDS codes
It is known that uniform (resp. paving) matroids correspond to MDS (resp. “almost MDS” codes). This post explains this connection.
An MDS code is an $[n,k,d]$ linear error correcting block code $C$ which meets the Singleton bound, $d+k=n+1$. A uniform matroid is a matroid for which all ... | {} |

# Changing Row Keys into Normal Rows

sfcostaper applies cosine tapering to the edges of the input data.
Cosine tapering amounts to multiplying the edges by
$$\sin^2\left(\frac{\pi\,x}{2}\right) = \frac{1+\cos{(\pi\,x)}}{2}$$,
where $x$ is the relative distance from the start of the taper.
sfcostaper works in N dimensions, the size of the taper in #th di... | {} |

### Dirichlet: 205th birthday
Johann Peter Gustav Lejeune Dirichlet was born on February 13th, 1805, i.e. 205 years ago, to a father who was a postmaster in Düren, one of the most Western towns in Germany.
At the high school, he learned from Georg Ohm. Dirichlet began his research of m... | {} |

# Strongly-Continuous linear functionals on $\mathcal{B}(H)$
Suppose $H$ is a complex Hilbert space and $$w: \mathcal{B}(H) \longrightarrow \mathbb{C}$$ is a bounded linear functional on $\mathcal{B}(H)$ such that $w$ is continuous even if $\mathcal{B}(H)$ is given the strong operator topology. I am supposed to prove ... | {} |

# Linear Algebra Complex Numbers
The solutions to the equation $z^2-2z+2=0$ are $(a+i)$ and $(b-i)$ where $a$ and $b$ are integers. What is $a+b$?
I simplified and got $(z+1)(z+1) = -1$ and now I'm not sure where to go from there. I did this but I'm not sure.
$(a+i)^2 = a^2 - 1$
$(b-i)^2 = b^2 + 1$
