The partial derivative of the expression for volume of a cone is

and when you integrate it you get what you should-the volume of a cone.

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? !

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;

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

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!

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!

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.

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

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

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.

I am pretty sure what their answer will be.

Hmmm.
