Spectrum derivative (or spectrum acceleration) - page 9

Mathemat:

The question itself:

The original meaning of the integral was area, volume, etc. Further on, with the development of analysis and the exact sciences, this meaning has expanded qualitatively. In physics, it can be work, flow, pressure, mass, moment of inertia and a thousand other quantities important to physics.

If I understand you correctly, discretization has nothing to do with it. It only shows the accuracy of the area calculation. The thinner the bars, the more accurate the area. But to be honest, I don't think I understand you, because I can't yet understand what you need it for.


So far, the dependence of the number of columns and the dependence of the accuracy of the area calculation on them is interesting
 

 

Valera, why do you need integrals, derivatives? Usually one sets a goal first. And only then do they choose a tool to achieve the goal. Which are a variety of mathematical methods.

Is this about your gloomy thoughts again?

 
trollolo:

I'll just put my thoughts here for now.

Replace the integral with the sum - it's fairer that way.

What does the sum have to do with it?
 
trollolo:

It has nothing to do with the sum.

It's a definite integral. And that's the sum.
 
Zhunko: Valera, why do you need integrals and derivatives?
Vadim, this isn't Valera, enough already. The style is completely different, and the presentation is better.
 

Although it is about populations in a biological environment, it is interestingly written about weighting factors and coefficients of influence.

Vadim, it's not Valera, stop it. The style is completely different, and the writing is more literate.

Alexei, the frequency analysis shows that it's Valera. Same style. A little rough on the image. But it's the same. The images are the same. Thoughts are muddled. The chips are new. That's how the chips used to be. Only different. He writes the same. Where did the old nickname go? The new one's almost the same as the old one. Just decided to change the image. But it's not easy.

Inappropriate jokes about Jews... Stupid attempt at a disguise. It's all very similar. He's posting in the same threads and flubbing in similar threads. A little more brazen. It was the same under that nickname at the end.

How did he read the whole forum in such a short time? I wrote a couple of posts on purpose to see how he reacted. It's Valera.
