What is Integration: Definition and 1000 Discussions
System integration is defined in engineering as the process of bringing together the component sub-systems into one system (an aggregation of subsystems cooperating so that the system is able to deliver the overarching functionality) and ensuring that the subsystems function together as a system, and in information technology as the process of linking together different computing systems and software applications physically or functionally, to act as a coordinated whole.
The system integrator integrates discrete systems utilizing a variety of techniques such as computer networking, enterprise application integration, business process management or manual programming.System integration involves integrating existing, often disparate systems in such a way "that focuses on increasing value to the customer" (e.g., improved product quality and performance) while at the same time providing value to the company (e.g., reducing operational costs and improving response time). In the modern world connected by Internet, the role of system integration engineers is important: more and more systems are designed to connect, both within the system under construction and to systems that are already deployed.
There's an integral over a 2-sphere ##S## with unit normal ##N^a## within a hypersurface orthogonal to a Killing field ##\xi^a##$$F = \int_S N^b (\xi^a / V) \nabla_a \xi_b dA = \frac{1}{2} \int_S N^{ab} \nabla_a \xi_b dA, \quad N^{ab} := 2V^{-1} \xi^{[a} N^{b]}$$which follows because the Killing...
I began this solution by assuming a = x+iy since a is a complex number.
So I wrote expressions of <a| and |a> in which |n><n| = I.
I got the following integral:
Σ 1/πn! ∫∫ dx dy exp[-(x^2 + y^2)] (x^2 + y^2)^n I
I tried solving it using Integration by Parts but got stuck in the (x^2 + y^2)^n...
Split the integral
$$\frac{Aa}{\sqrt{2\pi}}\int^{\infty}_{-\infty}e^{ikx}dk - \frac{A}{\sqrt{2\pi}}\int^{\infty}_{-\infty}|k|e^{ikx}dk$$
Apply the boundary conditions, this is where my biggest source of uncertainty comes from I doubled the integral and integrated from 0 to a instead of from -a...
Hi I'm having troubles with integration specially by substitution, I'm going to read a calculus textbook and i need recommendations of books with a good treatment on the different techniques of integration. I'd like a book with good exercises for self study and a exposure to integration of...
Is it possible to do the integration? That is the full question
I don't know where to start, try to use ##u=\cos x## and also ##\cos^2 (x) = \frac{1}{2} + \frac{1}{2} \cos (2x)## but failed.
Thanks
Good day !
I have a problem with the solution of the floowing integrals
Indeed i don't understand why they choose such borders for integral
b/a<c
y<c
doesn't mean that y<b/a !
many thanks in advance!
As we all know, integration by parts can be defined as follows: $$\int u dv = uv - \int v du$$ And the usual strategy for solving problems of these types is to intelligently define ##u## and ##dv## such that the RHS integral can easily be evaluated. However, something that is never addressed is...
This question arose while studying Cosmology (section 38.2 in Lecture Notes in GR) but it is purely mathematical, that is why I ask it here.
I do not see why the equation
$$H^2 = H_0^2 \left[\left( \frac{a_0}{a}\right)^3 (\Omega_M)_0 + (\Omega_{\Lambda})_0 \right] \tag{1}$$
Has the following...
In Griffith’s section 10.3.1, when proving why there is an extra factor in integrating over the charge density when it depends on the retarded time, he makes the argument that there can only ever be one point along the trajectory of the particle that “communicates” with the field point. Because...
I am reading a proof in Feedback Systems by Astrom, for the Bode Sensitivity Integral, pg 339. I am stuck on a specific part of the proof.
He is evaluating an integral along a contour which makes up the imaginary axis. He has the following:
$$ -i\int_{-iR}^{iR}...
I can calculate the value of the integration, it will be ##\frac{\sqrt{3}}{2}##
But if I draw the function and consider the area bounded by the curve and x-axis from x = 0.5 to x = 1, it seems that the area will be infinite because x = 1 is vertical asymptote.
Why can't I consider from "area...
my thinking was to have everything changed to a function that has cosine only...
##\int_0^{0.5π} \frac {1-cos^2x}{sin x + cos x}dx##
##\int_0^{0.5π} \frac {(1-cos x)(1+cos x)}{(1-cos^2x)^{0.5} + cos x}dx## ...
first of all is this integration possible? if so then let me know if i am on the...
So I am confused about a proof in which the formula for expected value of velocity, ##\frac{d\langle x \rangle}{dt} ##, is derived.
Firstly, because the expected value of the position of wave function is $$\langle x \rangle =\int_{-\infty}^{+\infty} x|\Psi(x,t)|^2 dx$$Therefore...
Hello,
I would like to is it possible to solve such a differential equation (I would like to know the z(x) function):
\displaystyle{ \frac{z}{z+dz}= \frac{(x+dx)d(x+dx)}{xdx}}
I separated variables z,x to integrate it some way. Then I would get this z(x) function.
My idea is to find such...

I am confused as to how exactly we integrate differential forms. I know how to integrate them in the sense that I can perform the computations and I can prove statements, but I don't understand how it makes sense. Let's integrate a 1-form over a curve for example:

Anyone have any idea how to perform the following two integrals?
##\int d\Omega n_{i}n_{j}## and ##\int d\Omega n_{i}n_{j}n_{k}n_{l}##
where the n is a unit vector.
I think in the case of "n da" you can see the denominator (1+x^2) as a constant, so
∫ ( sin(a) + M^2 ) / ( 1 + x^2 ) da
= ( 1 / ( 1 + x^2 ) ) * ∫ (sin(a) + M^2 ) da
= ( 1 / ( 1 + x^2 ) ) * ( -cos(a) + (M^2)a )
= ( - cos(a) + (M^2)a ) / ( 1 + x^2 )

Is this the way to go? This is my...

Hi,
I have this formula ## f(\theta, \phi) = \frac{sin \theta}{4\pi}##
I have this statement that say if I integrate this formula above on a sphere then p = 1.
what does integrate on a sphere means? I know ##\int_0^{2\pi} ## is used for the circle.

Performing the x-integration first the limit are x=y2 and x= -y2 and then the y limits are 0 to 1. This gives the final answer 2/5

Hi,
I'm wondering how can I get ## \phi(t) = A sin(\omega t) + B cos(\omega t)##
I know I have to integrate 2 times ##\ddot\phi = -\omega^2\phi##. However, I don't have any more explanation in my book.
I know A and B are the constants of integration.
