re Wolfram engine
hi
The screen shot below shows what Wolfram does to
Is there a way to tell the software that r is a function of h ?
You may recognise this from another thread.
Thanks,
Bob

Re: re Wolfram engine
It depends on the type of dependence between r and h...
The limit operator is just an excuse for doing something you know you can't.

Re: re Wolfram engine
Hi;
Why not just substitute that
In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

You mean (kh)^2, bobbym?

Well it's not exactly a tough integral is it? So you could also say "Why not just do it yourself?" And I have, of course!
A certain poster has read that post and used Wolfram to show I have done it incorrectly. And I have; if there's no relationship between r and h. So I just wondered if there was a way to get Wolfram to do it with the relationship. Substituting would probably be inadmissible.
Alternative question: Is there any way to get 'help' on what Wolfram can do? I see no 'help' link.

Nope, k is a constant, so I am thinking k = k^2.

Not that I know of.

Not in my world, please. That k is important to me. I'm thinking of naming it "Bob's constant". So you'll have to pay royalties just to use it!

Re: re Wolfram engine
Hi bob;
Sorry, but if there is a bigger bungler than the poster you are talking about it is me.
I have been playing with alpha and entered this
Integrate pi r^2 , h assuming r = f(h)

WHAT! You must be joking! At least you are on this planet! And in honour (honor?) of the respect I have for you I hereby grant you lifetime permission to use Bob's constant whenever you wish, free of charge and without the requirement to acknowledge whose constant it is.
Can't say fairer than that, can I ?
Got to go and do the washing up now, see you later.

Re: re Wolfram engine
Hi;
Here is another example, looks like you can get Alpha to output anything you like, plug this in.
Integrate[ pi r^2 ] with r =f(h)
I have for you I hereby grant you lifetime permission to use Bob's constant whenever you wish, free of charge and without the requirement to acknowledge whose constant it is.
Well, at least I have that going for me.
At least you are on this planet!
Wish I could get off but they won't take me. There is one major difference between me and that fellow, if you hit me on the head three times hard with a hammer you can change my mind.

If I were you, I would not reply to automated messages.

That is true, but replying to "him" doesn't have a point either.

anonimnystefy is correct. If he gets replied to he usually deletes his post. This is how he amuses himself.
