Re: Integration by Substitution
hi gAr
no it is not from the tangent,it is from facebook(suprisingly!).
The limit operator is just an excuse for doing something you know you can't.

Re: Integration by Substitution
Hi anonimnystefy,
That's really surprising! Has anyone solved it there? Is LaTeX enabled in facebook?

Re: Integration by Substitution
Hi anonimnystefy,
Okay.
Without LaTeX, it would be difficult understand the solution!

Re: Integration by Substitution
not quite,the solution exists wheter you find it or not.except if there is no solution at all

Re: Integration by Substitution
If we don't have a solution, it means it's in the closed book.

Re: Integration by Substitution
maybe there is no book that holds that exact solution.does the solution exist then?yes,you just have to find it.

Re: Integration by Substitution
Hi gAr;
In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

Re: Integration by Substitution
Yes,you are correct.I forgot to make a change of limits of integration when I used substitution.

Re: Integration by Substitution
Hi bobbym,
Could you write the solution of how you came up with a ZERO as an answer to that equation?
I try doing it but I could not came out with the same answer as yours.

Hi ClaudeAbastado;
Welcome to the forum. Which problem do you mean?

I believe these questions from the original post haven't been answered yet. I guess the only one remaining to be answered is #20
