Do you need maths in principle? - page 2

I thought the question was about the possibilities of nature, not the cockroaches in people's heads. What you point out is from the realm of specialists.

and even there I had no use for quadratic equations with integrals

No, people who have never counted how much wallpaper they need really don't need mathematics...

Retards don't need maths for the retarded...

Disabled people, the ones who are dying, don't need it...

But all these people are far from the bulk of people, while the bulk of people sometimes have to count the same rolls of wallpaper, and use the knowledge of geometry and even trigonometry ...

 
Mickey Moose:

For example?

For example - find the intersection of two trend lines.

Also - to calculate the angle of slope of the line (at a fixed scale).

 
Georgiy Merts:

Have you ever wallpapered, mate?

I've wallpapered. There are specially trained people for wallpapering. They can do the math. Life rarely requires more than sixth-grade maths.

In real life I've never used trigonometry, vectors, integrals, limits...

From high school only matrices. Terver and physics a little, more for the sake of interest.

Sorry for the immodest question... How old are you?


The "school stuff" has been said for a long time and is useless in 95% of cases in life. The point is that the "school stuff" gives you a chance to think and make the brain work. If it were not for this stuff, everyone would have become stupid long ago.)
That is why we do not make iPhones, but the americans make the so-called "school stuff" in their garages.

OK, let's say you need to calculate it for some reason. Can you convince me why it is necessary at all? If we do not take into account sporting interest and someone's fantasy.

I had similar problems, I solved them by crossing muwings or weighted average prices of bars, and again I don't need to calculate anything.

Speaking of iPhones, I am not interested in why or who makes them, I am interested in those who take them, especially on credit the size of three salaries. Do you have an iPhone?

These are different tasks, for crossing a moving average a 2-point crossing is counted, and for crossing a trend, if it is crossed, you need a cycle!

 
Evgeny Belyaev:

These are different tasks, the crossing of muwings is counted by 2 points, and for the crossing of trends, if they intersect, you need a cycle!


Okay, I'll explain it more clearly.

You take the sausage in the shop to eat it, but why do you count crossovers of trend lines?

 
Mickey Moose:


OK, let's say it has to be counted for something. Can you convince me why it's even necessary? Aside from the sporting interest and someone's imagination.

Well, the most obvious one is Gunn's square and his lines.

 
Mickey Moose:


OK, I'll make it clearer.

Sausage is bought in the shop to be eaten, but why do you count the trend crossovers?

There are two promising trends, one is stalling, the other is growing.... At the inflection point we will cover one, and increase investment in the other.

So you're not talking about advanced mathematics.
