    Red face Integration: What is wrong with my method?

    Hello, my name is Gina. I've been trying to do the following problem:



    I have a hunch that my error has something to do with me not using exponents properly... but I'm not spotting it. I thought a fresh pair of eyes would help. ^_^

    Anyway, if you could please tell me what I'm doing wrong with "my" method, I'd appreciate it.

    Thank you,
    Gina

    You are treating the term \frac{1}{x^2} as if it were a constant. The rule you are trying to use works when you have a^2-x^2 in the radical.

    Ohhh! Heh, I wasn't aware that 'a' had to be a constant ... I thought any term would be fine. ^^; So silly of me.

    THANK YOU!
