A soft warping of an amply modicum variation of Newton's calculus

I looked at your paper, your website, your Facebook, and your resume. You are a very interesting guy. I love your art. You are using everyday language in unusual ways, making it hard to understand your train of thought. It's interesting to say the least but there does not seem to be any intention to connect with your readers.

 

Can you express your idea in everyday language?

I posted particularly to establish a connection.

Anyway, looking at the image above, specifically the parts in red titled 'Sample' and 'Collapse' , what are your thoughts?

 

 

@Mathematic:

The sample is standard, of course.

The 'collapse' portion is non-standard.

 

The "sample" is there to show the difference between the default way of doing things and my way, as seen in the "collapse" portion.

 

Please comment on the non-standard portion.

My thoughts? Sadly although I can talk about the abstract theory of integration, specific integrals make my eyes glaze over. I couldn't do those problems even when I TA'd that class! I have no opinion about anything involving techniques of integration. Pretty much everyone on this site knows that material better than I do.

 

When mathematic says ...

 

The sample is an example of a standard method of integration involving square roots. What is the point?

... I am in no position to disagree. Sounds about right.

 

(Edit) That said, perhaps I'm being overly modest. I recognize the math you did. It seems like a standard exercise in basic integral calculus. Can you say what it is you find significant about it?

Of course, the sample part is a standard example.

 

The 'collapse' bit in contrast, is my invention/input.

No, the part labeled "collapse" is precisely what would be done in any Calculus text.

 

This is the first time hearing such data.

 

I had searched for 4 years, without finding the collapse regime.

 

Could you direct us to where the collapse bit exists, in standard texts?

Standard texts won't use the word 'collapse', that's what was said above. But any calculus text worth the paper its printed on will delve very deeply into 'u-substitutions' quite a lot. Go to your local library and check it out.

The paradigm described is not u-substitution.

 

 

/////DIFFERENCE - i:

 

Fundamentally, u-substitution applies for functions of the form ∫ f(x) f'(x) dx. (that is, when integrals contains some function and its derivative)

 

 

EXPLANATION_EXPERIMENT:

 

(A)

 

INITIAL_FUNCTION(a) = ∫ sinx cosxdx.

 

Let u =sinx, and du=4cosxdx. Here we see that the INITIAL_FUNCTION(a) yields the form ∫ udu.

 

In (A) u-substitution nicely applies.

 

 

 

(B)

 

INITIAL_FUNCTION(b) = √16 - x^2

 

Let u = 4sinθ, and du = 4cosθdθ. Here we see that the INITIAL_FUNCTION(b) does not yield the form ∫ udu.

 

In (B) u-substitution does not apply, such that "dx/dθ * dx" absorbs the solution.

 

 

 

 

 

 

 

 

 

 

/////DIFFERENCE - ii:

 

EXPLANATION_EXPERIMENT:

 

U-substitution when applied to trig integral forms that don't satisfy the fundamental requirement in DIFFERENCE - i, don't engender via my equation "dx/dθ * dx".

(B)

 

INITIAL_FUNCTION(b) = √16 - x^2[/size]

 

Let u = 4cosθ, and du = 4cosθdθ. Here we see that the INITIAL_FUNCTION(b) does not yield the form ∫ udu.

 

In (B) u-substitution does not apply, such that "dx/dθ * dx" absorbs the solution.

So, you 'prove' that this isn't u-substitution by using something different that what your 'collapse' does.

 

You use [math]x=4\sin\theta[/math]... why not try [math]u=4\sin\theta[/math]? And maybe not make a mistake in forming the du term.... "u = 4cosθ, and du = 4cosθdθ" is obviously wrong.

 

 

Lastly, is there any reason you can't use this forum's LaTeX capabilities? Your post here is very difficult to read and it doesn't have to be...

Typo purged.

 

What my collapse does was represented by the green segment, in my prior comment: dx/dθ * dx.

Yes, that was a bit confusing.

This should be a better explanation: https://drive.google.com/file/d/0B8H3Ghe4haTWbW1uVGxiZ3ZqbEk/view

 "dx/dθ * dx" is meaningless.  Did you intend "dx/dθ * dθ"?
