What you saw in that article is the total derivative of the volume of a cone. That is a different thing and its integral isn't the volume of a cone, and it shouldn't be, because you aren't differentiating the volume only with respect to h in the first place.

You claim, what the formula

isn't right?

Also give please the answer to the first question:

1. CALCULUS claims that the

function represented in drawing in the form of the line is the function schedule.

You agree, behavior of the line of the schedule of the y=f(x) function it isn't behavior of the function y=f(x) , because other function p=f(x) is represented in the form of the line? !

I have deleted repetitive posts. You do not have to post the exact same post just because it has not been answered immediately. Leave the post and wait for a response.

You are still posting to yourself multiple times, I have asked you not to do this especially when it is just a copy of an earlier post.

Please no more posts criticizing the forum.

Look this (that is emphasized with red and black lines):

[comment removed by administrator] Or one changes, or another. Otherwise they become dependent from each other. They will have the general argument - time. But cone volume - function of two independent variables.

BUT (!!!!!)

Hi, Bobbym!

Hi;

21122012 · 2012-12-09 06:27:40

What do you mean under the word "base"? If r and h vary, that

For example

But then

What than R?!

21122012 · 2012-12-09 06:51:46

The main difference of Structural Analysis (SA) from Calculus (C) is that in the C main instrument of research of functions differentiation is, and integration is considered as the return process.
In SA the main tool on the contrary is integration, and differentiation is considered as the return process.
In C it is mistakenly considered to be differentiation as a way from simple to difficult
Because of that that integration is a transition from simpler to more difficult it allows to consider that that doesn't allow to consider C. For example:
h ttp://vladimir938.eto-ya.com/files/2012/12/yx.jpg
If initially it isn't known that two various functions

special case at y=x;

have identical dependence from that the derivative doesn't allow to come two ways to these to two functions, because the formula

for function

leads to the wrong answer.
But SA shows why these two various functions have identical dependence from :

You try to combine incompatible concepts. r and h can't be independent variables and change at the same time.

21122012 · 2012-12-09 07:18:06

Look post 140!

At the left and in the center cone volume as function of two variables is shown. On the right cone volume - function of one variable = function of two variables being function of the same argument: t!

Calculus incorrectly considers lines on function graphics. It isn't necessary to give examples with lines on graphics. About the function schedule we will be able to communicate only after you will answer a question:

1. CALCULUS claims that the

function represented in drawing in the form of the line is the function schedule.

You agree, behavior of the line of the schedule of the y=f(x) function it isn't behavior of the function y=f(x) , because other function p=f(x) is represented in the form of the line? !

Therefore all of you time cite as an example a geometrical formula which has no relation to the concepts Calculus while you won't write down it or:

or:

!

Well.
I will show one real mistake. But usually after such my subjects in Russia deleted at once. I will try here. We look the link:
h ttp://en.wikipedia.org/wiki/Partial_derivative
We see a formula of a full derivative of volume of a cone on height:
We integrate this derivative and we receive... cylinder volume:
Here to you one real mistake!

Well. Only don't prove to me that the derivative of the sum is equal to the sum of derivatives always. Keep in mind that only the algebraic sum means!

I can't understand sense of that that you wrote. I showed animation on which on the right and at the left two independent variables are shown. And on the right - dependent. What I still should have made and I didn't make?

There are many formulas, but there are no what are necessary to us. Here they:

or:

I got it:

No!

It is

a formula of a general view. But you set conditions:

Now this formula looks so:

This record

has no relation to a formula

Probably it is related to other entry conditions. It doesn't make therefore further to read sense!

Hi, bobbym.
I claim that

function represented in drawing in the form of the line on function graphics.

Ask the best mathematicians, I am right or I am mistaken.

Also set the task: What function from

is represented in drawing in the form of the line on y=x^2 function graphics?

I am sure that any mathematician won't be able to answer this simple question. Because they yet don't know Structurual Analysis.

At the same time you will advertize the site and you will attract to it many new people.

21122012 · 2012-12-09 13:29:01

I probably should create the site and to remove a videoclip on YouTube where to tell to people as them make a fool at school of the mathematics teacher.

The joke.

The problem with those two questions is that they do not make much sense. You should find better words to explain your thoughts.

How no it have? At school studying of Calculus begins with studying of these lines. If they are incorrectly interpreted, the theory which on them is under construction can't be true.

anonimnystefy · 2012-12-09 13:42:36

They do not make sense because I do not understand what they mean.

21122012 · 2012-12-09 13:43:51

For example if you on the OX axis postpone radius length

, and on the OY axis the circle area , what geometrical figure will be represented in the form of the function schedule? If Calculus doesn't solve this very simple geometrical problem that it not the scientific theory and children's game in puzzles.

anonimnystefy · 2012-12-09 13:45:06

How do you postpone a radius?

x=r

practical task. Let there will be not an OX axis and the OR axis. Or let there will be everything so to what you got used only x - is radius.

21122012 · 2012-12-09 13:54:59

All right if to you difficult about radius let's solve such practical problem. On the OX axis you postpone the square party, and on the OY axis its area. Question: what geometrical figure will be represented in the form of the function schedule?

bobbym · 2012-12-09 14:05:23

Ask the best mathematicians, I am right or I am mistaken.

I am pretty sure what their answer will be.

I am sure that any mathematician won't be able to answer this simple question.

Hmmm.

No comment.
