http://math.stackexchange.com/questions/296869/finding-the-largest-set-where-a-complex-function-is-analytic
# Finding the largest set where a complex function is analytic I am considering the function $$f(z) = \frac{e^z}{\sin z - \cos z}.$$ So I solved for $\sin z - \cos z = 0$ and got $\pi/4$. But why is it $\pi/4 + k\pi$ and not $\pi/4 + k2\pi$ for the part of the complex plane where this function is not analytic? Thanks. - $$\sin z -\cos z=0\Longleftrightarrow \tan z = 1\Longrightarrow z=\frac{\pi}{4}+k\pi\,\,,\,k\in\Bbb Z$$ as the period of the tangent function is $\,\pi\,$ , not $\,2\pi\,$

# On the uniqueness of invariant states Federico Bambozzi, Simone Murro June 24, 2019 Given an abelian group G endowed with a T-pre-symplectic form, we assign to it a symplectic twisted group *-algebra W_G and then we provide criteria for the uniqueness of states invariant under the ergodic action of the symplectic group of automorphism. As an application, we discuss the notion of natural states in quantum abelian Chern-Simons theory. Keywords: none

# Math Help - Primes 1. ## Primes Prove that if one chooses more than n numbers from the set $\lbrace1, 2, 3, . . . , 2n\rbrace,$ then two of them are relatively prime. 2. Partition them as $\{1,2\},\ \{3,4\},\ \hdots,\{2n-1,2n\}$. Since there are $n$ parts, one part must contain two of the numbers, and hence two of the numbers are adjacent. Since adjacent numbers are relatively prime we are done.

Total number of voters = 15,000 Percentage of the voters who voted = 60% $$\therefore$$Percentage of the voters who did not vote = (100 – 60)% = 40% Actual number of voters who did not vote = 40% of 15,000 =$$\frac{40}{100}$$×15,000=6,000

# Quite a Quote! Everyday quotes for everyone. ## Noam Chomsky: Limits of debate “The smart way to keep people passive and obedient is to strictly limit the spectrum of acceptable opinion, but allow very lively debate within that spectrum — even encourage the more critical and dissident views. That gives people the sense that there’s free thinking going on, while all the time the presuppositions of the system are being reinforced by the limits put on the range of the debate.” -Noam Chomsky.

# Nanocomposites polymer/graphene stiffness Dependence on the nanofiller structure: the fractal model Авторы: Аннотация: The dependence of the elastic modulus of the nanofiller for polymer/graphene nanocomposites on the structure of graphene aggregates has been shown. It is established that this structure is defined by the dimension of Euclidean space, in which these aggregates are formed. The indicated structure is most accurately characterized by its fractal dimension.

# Lecture 4 The video titled Lecture 2-3 comes after Lecture 7. We continue on with Lorentz transformations, and define space-time separation. This allows us to define proper time and proper length, which are invariant quantities and contrast with coordinate variables, which aren't the same in all reference frames. We look at consequences of these definitions, describing the relativistic effects of time dilation and length contraction.

## Algebra 2 (1st Edition) The initial amount is $527$, the percent increase is $1.39-1=0.39$, and the growth factor is $1.39$. If for an exponential function $y=ab^x$ $a\gt0,b\gt1$, then it is an exponential growth function, and $b$ is the growth factor. Following the example, the initial amount is $527$, the percent increase is $1.39-1=0.39$, and the growth factor is $1.39$.

A real number has the argument equal to zero if positive or $\pi$ if negative: So, it is $2 \cos \pi + i \sin \pi$. $\sin \pi = 0$ so number is real; $\cos \pi = - 1$ so the number is negative.

# Antimatter creation from collision of photons Can you create antimatter by letting photons collide? • – NickD Jul 26 '17 at 20:39 • – heather Jul 26 '17 at 20:40 Photon-photon pair production can be represented by the equation $\gamma + \gamma^{'}\rightarrow e^-+e^+$, which basically means that the collision of two photons produces an electron and a positron (the anti-electron).

# Second Order Numerical Integration w/ Neumann Boundary Conditions I hope this is the right place to post this question. I'm trying to figure out how to run a numeric integration for a nonlinear second order ODE with Neumann B.C. I've started programming up Runge Kutta 4, but clearly without a boundary condition on the function, but only on its derivative I'm stuck. If anyone could point me in the right direction, or refer me to a text that discusses this problem I'd really appreciate it.

Suppose that the height of the ball $1$ second after you throw it is $25$ m. Then how many seconds will it take for the ball to reach the peak, from the moment you throw the ball?

Sum of exterior angles of every polygon irrespective of number of its sides is ${360}^{o}$. As it is a regular polygon, all exterior angles are equal and are ${30}^{o}$. Hence number of sides of the polygon is ${360}^{o} / {30}^{o} = 12$.
