Let us consider the infinite products ## p_{n}\,=\, 2\cdot 2\cdot 2 \cdot 2 \cdots 2 \,=\, 2^n## with ##n=1,\ldots ## . Clearly ##p_{n}\rightarrow +\infty## as ##n\rightarrow +\infty##. But ... | {} |
# Merkle Tree Height
I'm reading about Merkle tree signatures, and I would like to know whether the security of that scheme depends on the height of the tree, or does it only depend on the hash function being resistant to collision?
If you look at exact security, the height matters. The reason is that it defines the ... | {} |

pls help me solve for the roots of the quadratic trinomials
2. This isn't a homework service. You have to show that you at least made an effort to try them rather than just getting other people to do it for you.
We need proof that you actually tried, and then we can help you on parts that you get stuck on or cannot d... | {} |
## Automatic differentiation and gradient tape
之前我们介绍了Tensor 以及在其上的操作，下面我们介绍一下自动微分技术，---用来优化模型参数的关键。
tensorflow 提供了用于自动微分的API，来计算一个函数的导数。一种更接近数学的求导方法是：先写一个python函数，封装好对参数的运算。然后使用tf.contrib.eager.gradients_function 来创建一个函数计算上面封装好的函数的导函数（可指定对哪个参数求导）。同时，只要嵌套调用该函数，即可求高阶导。

use the law of sines then solve for x $\frac{ \sin A }{ a }=\frac{ \sin B }{ b }=\frac{ \sin C }{ c }$ $\frac{ \sin 50 }{ 2x+6 }=\frac{ \sin 50 }{ 4x}$ does that help?

Time isn't always the determining factor in an MTTF calculation. Step 4: Failure Rate is just the reciprocal value of MTBF. Step 2: Note down the value of F. It is the number of failures occurred in a system. More simply, it is the total working time divided by the number of failures. MTBF, along with other maintenance... | {} |

At INFORMS, I saw a talk by Jingxing (Rowena) Gan, about her paper Inventory, Speculators, and Initial Coin Offerings (joint with Gerry Tsoukalas and Serguei Netessine). I really liked the model, so I thought I'd give my take on it. Although the paper is f... | {} |

A population of values has a normal distribution with $\mu =99.6$ and $\sigma =35.1$. You intend to draw a random sample of size $n=84$.
Find the probability that a sample of size $n=84$ is randomly selected with a mean between 98.5 and 100.7.
$P\left(98.5<\stackrel{―}{X}<100.7\right)=$?

# Computation of Hankel Transform using FFT (Fourier)
To address circular symmetric cases of 2D Fourier Transformations the so called Hankel Transform can be applied (for a detailed derivation of the relation between the 2D Fourier transform and the 1D Hankel transform see Link).
