The purpose of this article is to let oneself learn Goldbach conjecture study of specific methods, specific reference Pan book "Prime Distribution and Goldbach conjecture", in this I will prove the details as far as possible to write more detailed,

Foundataions of machine learning: Rademacher complexity and VC-dimension (2) (1) growth Function) Before introducing the growth function, let's introduce an example which will help you understand the growth function. When the input space is $ \

1. What is a shard of $ \ mathbb F $? As the formula field of $ \ mathbb F $ contains the smallest domain, and $ \ mathbb F $ itself is a domain, the formula field of $ \ mathbb F $ is itself.   2. It is proved that gsuss Integer Ring $ \ mathbb Z [\

One.1. $ (\ln 5 \cdot 5^x +e x^{e-1}) dx$2. $e ^{x+1}$; Consider the following limits\[F (x+1) = \lim_{t\to +\infty} \exp \frac{\ln\frac{t+x}{t-2}}{t} = \exp (\lim_{t\to +\infty} t{\ln (1+\frac{x+2}{t-2})}) =\exp (\lim_{t\to +\infty} {\frac{(x+2) t}{

Maximum value for $ (\cos x+2) (\sin x+1) $Solution: Set $ $f (x) =\cos x \sin x +\cos x+ 2\sin x +2$$make $t=\tan{\frac{x}{2}}$, then$$\sin x=\frac{1}{1+t^{2}}; \cos x=\frac{1-t^{2}}{1+t^{2}}$$Bring in $f (x) $ to find the maximum value of the

1. geometric formula Triangle: 1. Half perimeter P = (A + B + C)/2 2. area S = AHA/2 = absin (C)/2 = SQRT (P-A) (p-B) (p-C )) 3. midline MA = SQRT (2 (B ^ 2 + C ^ 2)-a ^ 2)/2 = SQRT (B ^ 2 + C ^ 2 + 2 bccos ()) /2 4. ta = SQRT (BC (B + C) ^ 2-A ^ 2)/

8. it is proved that each semi-positive definite matrix has a unique square root of the semi-positive definite number. That is, if $ A \ geq 0 $, there is a unique $ B \ geq 0 $ that satisfies $ B ^ 2 = A $.     Proof: $ A \ geq 0 $ indicates the

NaN is an abbreviation for not a number. It is a numeric type value, typically in a floating-point calculation, that represents a value that is undefined or cannot be represented. Also, you cannot use the equality operator (= =) to check NaN. In the
