### Multiplication is the inverse of division When working with multiplication and division it is useful to understand that they are the inverse of each other. That means that multiplication can be used to undo division and vice versa. For example, 25 ÷ 5 = 5 and 5 × 5 = 25.

Boundedness of Sine X over X Theorem Let $x \in \R$. Then: $\size {\dfrac {\sin x} x} \le 1$ Proof From Derivative of Sine Function, we have: $D_x \paren {\sin x} = \cos x$ So by the Mean Value Theorem, there exists $\xi \in \R$ between $0$ and $x$ such that: $\dfrac {\sin x - \sin 0} {x - 0} = \cos \xi$ From Real Cosine Function is Bounded we have that: $\size {\cos \xi} \le 1$ $\blacksquare$

Collect terms in a sum that differ only by their numerical pre-factor. This is part of the default post_process function, so does not need to be called by hand. Note that this command only collects terms which are identical, it does not collect terms which are different but mathematically equivalent. See sort_sum for an example.

Say we have a matrix A of shape N x M, which can be viewed as a collection of N vectors of shape 1 x M. The code below gives us the correlation matrix of A: To visualize it, just use plt.matshow(A_corr). If N is so large that the figure could not provide a clear insight, we might alternatively use histograms like this:

They are used by a company to track their projects and the time employees spend on a given project. ## Exercise Select all the information from the table Project.

This is joint work with Maria Luisa Colasante, Universidad de los Andes, Venezuela. Let X be a topological space. The topological closure of the diagonal \Delta = {(x,x): x\in X} is a symmetric relation on X. Our starting point is the well-known proposition that a topological space is T_2 if and only if cl(\Delta) = \Delta. We investigate the closure of the diagonal on T_1 spaces and characterise those equivalence relations that arise as the closure of the diagonal of some T_1 space.

# Which element on the periodic table has a total of 16 protons? $Z$, the atomic number is the number of protons, positively charged nuclear particles. But $Z$ defines the identity of the element, If $Z = 1$, the element is hydrogen, $Z = 2$, the element is helium, .............$Z = 16$, the element is sulfur.

## Photoelectric effect I like to get the data of the actual photoelectric experimentation. I have tables with the work function, thus I can compute the threshold frequency, but I believe that introduces at least two errors. I would like to get the frequency obtained directly from experimentation. Anyone can help me?

# Determinant evaluations and U(n) extensions of Heine's 2\phi1-transformations ### (6 pages) Abstract. We give new proofs for U(n) extensions of Heine's three 2\phi1-transformation formulas that were recently discovered in another paper by the authors. These new proofs proceed by combining Heine's original transformation formulas with certain determinant evaluations. As a by-product we are able to generalize two of the U(n) transformation formulas. The following versions are available:

# A light and a shadow Geometry Level 2 A rectangular billboard $ABCD$ is illuminated by a lantern $E$ and casts a shadow in the $xy$-plane. The positions $(x,y,z)$ of the lantern and the billboard's vertices are $A = (0,0,0), \quad B = (0,3,0), \quad C = (0,3,2), \quad D = (0, 0 ,2), \quad E = (3, -1, 4).$ What is the area of the shadow? Assumptions: The light source is a point and the billboard has zero thickness. The ground is the $xy$-plane. ×

1. ## simple integration $ \int^{\infty}_{-\infty}x^{-1/2}e^{x/2}dx $ 2. Edit: sorry it was wrong 3. Hello, This is weird because it is not defined for x<0... $ Well intuitively when say x>1, $e^{x/2}$ grow faster then $\sqrt{x}$ . It follows that $\int_1^\infty \frac{e^{x/2}}{\sqrt{x}}\,dx$ diverges and hence so is the original integral.

# Ubuntu – Wireless headset can’t be enabled My Logitech H800 normally works fine with Ubuntu, but sometimes, I think when I unplug and replug the USB adapter, it stops working. It is listed in sound settings under outputs, and clicking it highlights it, but sound is still played through the builtin sound hardware. Running pactl list sinks does not show it. My workaround is running pactl exit, after which all works fine. I just discovered it now but I don't expect it will be a permanent fix.

# How do you find the slope of the secant lines of f(x) = -x^2 through the points: [-2, -4]? Feb 8, 2018 $6$ #### Explanation: $\text{the slope of the secant line is}$ •color(white)(x)(f(b)-f(a))/(b-a) $f \left(b\right) = f \left(- 2\right) = - {\left(- 2\right)}^{2} = - 4$ $f \left(a\right) = f \left(- 4\right) = - {\left(- 4\right)}^{2} = - 16$ $\Rightarrow \frac{- 4 - \left(- 16\right)}{- 2 - \left(- 4\right)} = \frac{12}{2} = 6$

https://socratic.org/questions/how-do-you-find-the-taylor-series-for-e-x-2

# How do you find the taylor series for e^(x^2)? 1+x^2+(x^4)/(2!)+(x^6)/(3!)+(x^8)/(4!)+cdots. This converges to ${e}^{{x}^{2}}$ for all values of $x$. This can be obtained most simply by taking the well-known Taylor series for ${e}^{x}$ centered at 0, which is 1+x+x^2/(2!)+x^3/(3!)+x^4/(4!)+cdots, and replacing $x$ with ${x}^{2}$. You can also try using the formula f(0)+f'(0)x+(f''(0))/(2!)x^2+(f'''(0))/(3!)x^3+(f''''(0))/(4!)x^4+cdots, but that is a much less pleasant approach.

The generalization to higher $p$ may involve higher-order derivatives as follows: \begin{align}K_p &= \int_0^{\pi/2} dx \frac{x^{2 p}}{1+\cos^2{x}} = \frac1{2^{4 p-1}} \int_{-\pi}^{\pi} dy \frac{y^{2 p}}{3+\cos{y}} \end{align} So define, as before, $$J(a) = \int_{-\pi}^{\pi} dy \frac{e^{i a y}}{3+\cos{y}}$$ Then $$K_p = \frac{(-1)^p}{2^{4 p-1}} \left [\frac{d^{2 p}}{da^{2 p}} J(a) \right ]_{a=0}$$ […]

# Tame submanifold Let $M$ be a manifold of dimension $m$ and $N$ a submanifold of dimension $n$. Then $N$ is termed tame in $M$ if for every point $x \in N$, there exists a neighbourhood $U$ of $x$ in $M$ such that the pair $(U, U \cap N)$ is homeomorphic to the pair $(\R^m,\R^n)$ where $\R^n$ is viewed as a linear subspace of $\R^m$. An example of a submanifold which is not tame is the Alexander horned sphere in $\R^3$.

## Introductory Algebra for College Students (7th Edition) Perimeter=$2+2\sqrt2$ inches Area=$1$ square inch Perimeter is the sum of the lengths of the sides. $P=2+\sqrt2+\sqrt2$ Combine like radicals. $P=2+2\sqrt2$ The area of a triangle is one half the product of the base and height. $A=\frac{1}{2}bh$ $A=\frac{1}{2}(\sqrt2)(\sqrt2)$ Use the product rule for square roots. $A=\frac{1}{2}\times2$ Simplify. $A=1$

## Calculus (3rd Edition) Given $$\sum_{n=1}^{\infty}\frac{n !}{n^{3}}$$ Compare with $\displaystyle\sum_{n=1}^{\infty}\frac{1}{n^{2}}$, which is a convergent series ( $p-$series with $p=2$) and for $n\geq 1$ \begin{align*} \frac{n !}{n^{3}}&=\frac{n \times(n-1) !}{n^{3}}\\ \frac{n !}{n^{3}}&=\frac{(n-1) !}{n^{2}}\\ & \geq \frac{1}{n^2} \end{align*} Then $\displaystyle\sum_{n=1}^{\infty} \frac{n !}{n^{3}}$ also converges.
