Discussion Overview

The discussion revolves around a participant's confusion regarding a mistake made in the context of indefinite integration, specifically questioning the implications of constants of integration and their potential equality.

Discussion Character

  • Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant expresses uncertainty about their mistake in the context of indefinite integration and seeks clarification.
  • Another participant asserts that the mistake involves the assumption that the constant of integration must be the same across different integrals.
  • A further reply emphasizes that in indefinite integration, the constant does not need to be the same, suggesting that the constant in one integral can account for additional terms.
  • There is a mention of definite integration, where boundaries must be applied, and a specific example is provided to illustrate that this leads to no contradiction.
  • A participant acknowledges understanding after receiving clarification regarding the nature of constants in indefinite integration.

Areas of Agreement / Disagreement

Participants appear to agree on the point that constants of integration do not need to be the same in indefinite integration, but the discussion contains varying levels of understanding and clarity regarding the implications of this concept.

Contextual Notes

The discussion does not resolve the initial confusion about the mistake, as it centers on clarifying the role of constants of integration without reaching a definitive conclusion on the participant's original question.

Obviously it is my mistake but i am wondering what is the mistake i made. First of all, i didn't know how to type math in this forum so i attached a word document with my "idea"

Your mistake lies in assuming that the constant of integration must be the same "c".
It won't be.

could you explain a little more?
 
nicksauce , i got an email that you replied but i can't see your post
 
In an indefinite integration you will get a constant c. It doesn't have to be the same in b oth integrals so the constant in the right integral will cover for the addition of '1'.

In definite integration, you will need to put the boundaries on 1 to.
So it will be lie:

[tex]1_{x=b}-1_{x=a}[/tex]

Which is of course zero, and therefore there is no contradiction.
 
elibj123, thank you very much I was referring to indefinite integration and i understand now. Again thanks
