0=1 or is it my mistake?

    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?

    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:


    Which is of course zero, and therefore there is no contradiction.
